Lets see if the new thread can help me with this issue that I'm still fighting. 97 Toyota Tercel with a 4E-FE. Efi is a simple MAP sensor system with an electronic distributor, one 02 sensor and not much else. Pretty normal for a late 90's toyota, almost identical system to a 4AFE. I have thus far replaced the distributor (old one was completely knackered), MAP sensor, ISCV (old one was clogged to poo poo), cleaned the TB, seafoamed the engine, plugs, O2 sensor and engine temp sensor. The issue: cold idles perfectly. As the car heats up, the idle reduces in speed (normal) but also gets quite rough and lumpy when the car is in D or R (in neutral it's ok). This is fine during the day, but putting electrical load on by switching on the headlights makes the idle drop down to an uncomfortably low speed that causes the steering wheel and whole car to shake. It never stalls, it never hesitates taking off from a stop, never stutters, drives perfectly. It just doesn't seem to be able to compensate for added electrical load by bringing the idle up slightly. Having an indicator going while you're stopped in D makes the idle fluctuate up and down in time with the indicator turning on and off. I'm at a loss as to what else to look for/do. It's like the car just won't behave as designed and it isn't a faulty component that I can find.

Intake manifold has a grand total of 3 vacuum lines (booster, pcv, evap canister). It isn't leaking. I know conventional wisdom indicates that solid tappet Toyotas never go out of spec and even when they do, it makes gently caress all difference to anything, but could loose clearances do this? Forgot to mention: chucked a set of junkyard injectors at it, made no difference at all, so I'm assuming the injectors are OK at 190,000km.

IAT readings are sensible. Don't think the car has the ability to correct long-term, or if it does both scan tools I've hooked to it can't display them for some reason (modern cars work perfectly). It isn't OBDII fwiw. I can't picture it being anything a/f ratio related like a temp sensor because it runs perfectly, it just won't idle fast enough when it has electrical load.

Slavvy posted:Good idea, I'll try this when I get home. Quoting for progress. Car runs with every sensor disconnected. Connecting them one by one led to not much change in idle until the engine temp sensor, which caused a noticeable drop (like 450-500rpm in D/R with low beams, indicator and windscreen wipers going). Guess I have to re-examine that, now.

kastein posted:AquarianFire, the injectors weren't at fault, if they get told by the ECU to run that fast, they do. Something was screwy with the fuel management system and it probably wouldn't have cost that much to fix it, but oh well. I looked at the wiring diagrams and it appears that it was a modern engine with upstream catalytic converters and four oxygen sensors. If anything since half the engine was running rich I would have put my money on an upstream O2 sensor being worn out or damaged. The reason this causes stuff like that is that the oxygen sensors detect unburned oxygen in the exhaust. If one is reading the wrong value, or there's an exhaust leak that's letting in extra oxygen upstream of the sensor, they crank the fuel input up more to compensate for the "lean condition" they see, which doesn't help because the sensor's hosed or there's an air leak that's throwing the reading off, so you end up with every cylinder that sensor is reporting on running full-rich mode. The idle speed is reasonable if it's warm and you have no electrical stuff going. Turning on the headlights, then the wipers, then the indicator makes the idle progressively drop each time when it's in D. It just can't seem to bring the idle up to compensate but I don't know if that's because it is physically unable to, or if it's getting a bunk signal from something and running too rich for the temperature. I'll replace the coolant temp sensor because I'm running out of poo poo to throw at it; at this rate I'll have an entirely new engine management system and still no fix. At least parts cost a pittance. Motronic posted:No. I don't know where he got that idea. Nah. Spinning one tyre on an open diff is a great way to shatter the spider gears. When I worked at toyota we were doing Hiace diffs all the time because of over-zealous courier drivers parking them in mud and spinning up one of the wheels. There was a petition of sorts to convince Toyota to fit them with the Hilux LSD to stop this happening.

Assuming you don't have a scan tool that can go beyond just looking at fault codes, unplug an injector and stick a pulse led on it to see if they're getting a signal. Has it got an immobiliser? And is this a 1SZ or a 1/2NZ engine?

mr.belowaverage posted:No immobilizer, looks to be the 1nz-fe. It's basically a little round plastic disc with an LED inside and two terminals. You plug it into an injector connector to see if the injector's getting a pulse - safer for the ecu than a test light. The fact that it's no fuel AND no spark makes me think CKPS, look at the live data and see if you can see both crank and cam sensor signals. The 1NZ is by far the better of the two engines. They're usually extremely dependable; they have like two issues, both of which you can avoid if you just change the oil like a sane person.

More Tercel adventures. I bought a vacuum gauge of decent quality and hooked it up. When the car is hot and idling in neutral, the gauge actually reads above the 'healthy' range. I don't understand how this can be since it's a 4EFE and not an F1 engine so theoretically shouldn't be drawing more vacuum than normal. When I put it in D and put a bunch of electrical loads on it so the idle starts chugging as it is wont to do, vacuum drops into the 'normal' range. I don't understand. How can my car have super manifold vacuum? I expected a leak or something. This is really frustrating because I genuinely believed the gauge would reveal something useful and instead all signs point to a perfectly healthy engine that just won't idle for poo poo. e: worth mentioning the needle very rapidly flickers like half a point consistently, but I'm putting this down to the idle just being shaky as gently caress and not an actual issue.

Krakkles posted:What kind of vacuum gauge did you get? "Healthy" and "Normal" are not vacuum readings. Yes it is, that's (partly) what a vacuum gauge is for. Normal being around 17-22 inches of mercury, my car is around 25. I don't know how to answer your question beyond it being a vacuum gauge explicitly designed for this purpose. I was actually hoping to discover incorrect ignition timing or something like that.

Motronic posted:I think he was getting at the fact that you used "normal" as a measure. None of that matters diagnostically. What matters are real number and how it's moving in which conditions. Which article...? Also, every diagnostic vaccum gauge I've seen has a green zone around the numbers I stated that's 'normal'. Vacuum readings don't vary much from engine size/configuration as long as there's no forced induction involved; an engine in good condition and a good state of tune will always pull around 18-22 inches. My engine pulls more than that which makes no sense. The needle doesn't fluctuate or flutter or anything, it just sits steady with a shaking that matches the idle shake.

Motronic posted:Sorry, forgot to link it: I've looked at that site, it does none of those things. In every respect it behaves like a normal engine except for the vacuum being quite high at idle. It idles around 900 without load when it's fully warmed up; putting it in D and switching on all the lights and wipers makes it drop to around 500. It never stalls or hesitates, it just has a really low chugging idle. I'm due for a cambelt and it has a leaking crank seal so the belt could be stretched, maybe? It's the only explanation I can think of because it's the only thing I haven't hosed around with.

some texas redneck posted:The 900 RPM idle easily explains the high vacuum. Yeah I have, as well as a replacement map sensor and a rebuilt distributor. The latter was definitely making it suffer because it was leaking oil internally and had a cracked coil. I got a noticeable increase in power after doing this but the idle didn't change which steered me away from anything ignition related. The belt tensioner is just a manual one that you set and forget.

melon cat posted:2009 Hyundai Elantra GLS. The small triangular black panel on the inside of the door opposite the mirror pries of. Start at the top. It may have a little tweeter built in, the plug will be tucked down behind the door card but you can tug it out and disconnect it (or just let the whole thing dangle). There are three 10mm nuts holding the mirror on with studs, there may also be a plastic clippy type thing that you just pull on to remove. The wiring for the mirror will have a connector down behind the door card, clipped to the skin. You can usually undo these without taking the door card off, but if you absolutely have to do it it's easy and simple.

If I get on the highway within 15-20 minutes of starting the engine, it has trouble upshifting enough. Change your trans fluid and hope the trans isn't rooted beyond repair. Usually when a car does something like this the best course of action is not to just keep driving while it gets worse.

Raluek posted:I don't know anything about these cars, but is it possible that it's an electronic auto that isn't getting the correct tps reading? Like, it thinks you're at WOT all the time so it tries to hold the gear as long as possible? My first thought was vacuum modulator, but I'd hope they aren't still using those on a car that new. On that car engine computer and trans computer are the same thing.

In this situation you should take the shoes off, clean the back plate, apply some grease to the little shoulders where the shoes touch the plate and use some sandpaper to chamfer the sharp edges of the shoes. Never fails.

My car takes NGK plug BKR5EY-11. I can get BKR5ES-11 for next to nothing and have fitted those with no apparent issues. What is the purpose of the v-grooved electrode? I remember reading somewhere that it's an anti-fouling measure but I can't imagine how it would make any difference and after several thousand km my plugs aren't fouled at all despite it being an old Toyota.

totalnewbie posted:It's to theoretically control the location of the spark better for ignitability. The spark preferentially goes to edges, so having the V-groove means the spark preferentially sparks towards the center of the plug, rather than all around the edges. It's not an anti-fouling measure. Will it make any difference if I use one or the other on a 1.3L engine with 88 horsepower and 200,000km?

The function of an anti roll bar is to counteract body roll; they're on practically every car with every suspension design (yes I know corvettes blah blah shutup) because they're a cheap and extremely effective way to firm up handling whilst having good ride comfort/stability in a straight line. Even the live-axle mustang has one. I don't think the type of suspension has any bearing on it whatsoever because every modern macpherson car I've seen has the swaybar connected with dainty, sometimes plastic links that aren't really any good for transmitting loads outside of vertical. Other suspension designs like double wishbone, simulated pivot, super strut etc all use the same principle with similar designs. Sharknose BMW's are one car I can think of where the sway bar fitted directly into the lower arm but I don't think it did anything beyond making the wheel shake annoyingly on e21's if your wheel alignment and bushes were anything other than perfect.

Do me and everyone else reading this an enormous favour. Remove your broken mirror from your car. Then take a picture of both mirrors side by side with the mating surface facing the camera. To clarify: the image where you have circled a hole in green is a picture of the door. Not the mirror. The only parts of the mirror on the inside of the door is the connector and the three studs with 10mm nuts on them. e: the only other possibility I can see here is that the factory mirror has a plastic dowel that slips into that hole and the aftermarket mirror doesn't. In which case: don't worry about it and just put the mirror on the car. Slavvy fucked around with this message at 07:49 on Feb 20, 2015 |

Reverse is a dog gear so it could be that the teeth just aren't lined up; normally you would put it in neutral (with the engine running) and pump the clutch to try spin the shafts a little bit and let it engage. Not being able to get into gears with the car switched off doesn't really tell you anything. e: fucknaaaaaaaag!!

ROFLburger posted:So I got the car assembled and running. drove around the block, but could not engage reverse. I tried a few things and found that while stationary, cycling into a few of the drive gears before attempting to engage reverse does the trick. Popping it into 1st -> 2nd -> 6th (or whatever) and then reverse engages perfectly smooth. Anyone know what the hell that's all about? Is engaging the other gears first like slightly rotating the shaft enough to get dog teeth in on reverse? Seems totally normal. Do as instructed above.

I've searched Kia Sportages and Saturn Vues and recommended them to her but I'd like some more varied opinions. I can speak to the current sportage being extremely reliable. I don't know if your market gets the 2.0 but the 2.4 is grunty, solid and reasonably fuel efficient. There was a recall concerning the trans cooler leaking into the radiator but this may or may not have affected your market and certainly won't matter if she's buying new. It also has a 6 speed auto which puts it above most competitor vehicles AFAIK; the difference is noticeable and it's a trouble-free unit in general.
