I would test the tps if you haven't already, make sure it's operating. I'm guessing it has a range and is more than a WOT switch. If that checks (hopefully it doesn't and this is simply a bad tps), then test from the tps connector to the ECU pinout. It appears that the iacv is working correctly once the tps signal opens, so I'm thinking that the ecu is getting bad info from the tps.

If that checks (hopefully it doesn't and this is simply a bad tps), then test from the tps connector to the ECU pinout. I have replaced the idle speed control motor and the TPS twice. I've checked my wiring splice for the TPS connector, to make sure it hasn't come undone, and it's not shorting on the throttle bracket. Each time this happens though, the computer reports an arbitrary throttle position, sometimes 25% or higher. Unless there's an issue with the PCM itself... It never did this on the stock setup.

the TPS is just a variable resistor right? any extra resistance in the circuit would make that happen. there's got to be a loose connection/corrosion somewhere, maybe at the ECU end. I say go nuts with some contact cleaner and a toothbrush on every connector even close to the TPS.

I've been spitballing with someone from the A-body board over Messenger. They are suggesting that the tune could be incorrect. As I have mentioned before, this build is a bucket of GM Legos poured into the engine bay of this car. I reused a number of stock components, and the PCM is from a 1997 Monte Carlo. The A-body member posits that, because I am using the MC PCM, somewhat modified, the actual airflow isn't matching what's expected in the tables. Grand Am throttle body and mass air flow sensor, stock Century manifold absolute pressure sensor. The LA1 TB is larger than the L82/LG8, so it's allowing more air into the engine than expected. That would also explain the constant P0171 lean code I've had from day one. I sent an e-mail to Milzy with a link to that video. Hopefully he can come up with something. I'll probably call him soon too to discuss the tune.

During idle, the throttle body is closed and the air flows through the idle air control motor, correct? Just making sure it's not driving the throttle blade directly (pretty sure that's a more modern design more common on drive-by-wire). Anyhow imo if the idle air isn't moving through the throttle body, I don't see how it affects the idle even if it is oversized. Your mix and match components may be contributing to the persistent lean code, but should be unrelated to the high idle. If you blip the throttle while it's misbehaving, does it return to a more normal idle, or back to high idle? I find it strange that the pcm isn't making any apparent attempt to lower the rpms. If you can see that the input sensors are reporting normally, and the idle air motor is getting the right signal (perhaps as fully closed as the idle table allows), it may be pointing to an unmetered air leak?

After talking on the phone with Mike Miller, I think the problem is my dirty rear end hacking in the TPS connector. I didn't solder the wires. I just twisted and taped them. The only time I was able to catch this with any sort of scanner handy, throttle position was reported at 27%. The computer isn't trying to calm things down because it thinks the throttle is being held open. I guess I need to buy a soldering iron and melt some metal.

Crimp and heat shrink is probably the ticket here.

Upon further inspection, one of the wires was tapeless and possibly touching the throttle cable bracket. That would explain the seeming random nature of the issue. At some point in the near future, I will probably solder the wires. For now, I have rerouted the wires away from the throttle bracket, and once I get a hold of some more tape, I will liberally apply some. Mike also reiterated a probable cause for my persistent P0171 code: the rear valve cover ventilation hole. It's essentially open and causing a vacuum leak, because I have nowhere to put a hose. I will probably have to drill a hole in the coupler between the MAF and TB to insert the hose.

Heat shrink crimps - best of both worlds. Sealed up against the elements, but won't be prone to cracking from vibrations like solder would.

Tug on the wires once crimped to make sure they won't just fall out. for that, I would prefer to solder, though. I personally have never had any issue with the solder cracking boogey man. It's not a space shuttle. Twist and tape is... suboptimal for anything other than *very* temporary/test connections. Electrical tape is an insulator, not a structural component. edit: source: I used to install mobile electronics semi-professionally, as in I worked for a shop and did it for a living. poo poo I put in my personal vehicles over a decade ago, possibly two, is still working.

I have a ~$20 stripper/crimper combo from Commercial Electric (Home Depot's store brand), and it does decent crimps. But run far away from the $5-$10 poo poo at Walmart/Harbor Freight/any flimsy crimper+stripper combo. I never did it for a living, but I know the electrical work I've done on my own car will outlast the car (engine harness repairs, plus the typical stereo + sub stuff).

Coulda been a hell of a lot worse. That looks fixable with a 12 pack of beer, a mallet, and basic hand tools. What happened? And how loudly is George cussing at you right now?

I rear ended a Crown Victoria while entering a highway. The other driver was surprisingly calm about everything. He photographed my license, insurance card, damage, and license plate, and that was pretty much it for the encounter. No police were summoned. It ended as amicably as such a situation could. George is pretty pissed. I flat spotted the front tires, since I don't currently have functioning ABS. Made it home fine though. More pics in the morning as I assess the extent of injury. Initial inspection showed largely cosmetic damage, though the front cooling fan is wasted.

If it makes you feel any better, GM made ABS optional on much of their lineup for several years (from the mid-late 90s up until the feds made it mandatory). My 06 Ion doesn't have it, but it has drat near every other option (sunroof, PW, PL, PM, MP3/CD player with aux in, Onstar, compass, keyless entry, outside temp display, automatic headlights, etc). I think the only available factory options missing are the automatic transmission, leather interior, and ABS. I was guessing either a land barge (Crown Vic) or a smaller truck. I'd guess you're going to find a tweaked upper radiator support and a little bit of damage behind the bumper. I bet the fender pops back into place as soon as the radiator support gets hammered out. Glad to hear the CV driver wasn't a dick. randomidiot fucked around with this message at 07:06 on Jun 24, 2017 |

We've all rear-ended someone who probably shouldn't have stopped in the first place (I assume that is what happened here). The saving grace is that it will probably only happen once to you.Yu-Gi-Ho! posted:If it makes you feel any better, GM made ABS optional on much of their lineup for several years (from the mid-late 90s up until the feds made it mandatory). I consider that a good thing, GM ABS sucked rear end. When I lived in Nebraska with N-Bodies I would disable ABS so winter driving was less scary. Also, had a 2004 Grand Prix as a rental once, it is so goddamn fun having a rental car without ABS... Just sayin'.

The saving grace is that it will probably only happen once to you. Yes and yes (did exactly that in my 850, zero damage but my ins still paid out. I should have caused an accordion wreck in my E30 on an onramp when traffic suddenly stopped while I was looking in my side mirror, but managed to swerve into the grass median and hit nothing because E30. Sorry bout your damage there, at least it appears minimal.

I've tagged someone when they started to make a right turn... then decided not to. Dedicated turn lane w/yield sign. They started to take off, so I looked to my left to see if I was clear and oh hey there's an ambulance comi*CRUNCH*FUCKKKKKK Scratch on their car... $3000 in damage to mine.

It was a literal scratch on their car, a couple of inches long. I got them with the RF corner of my Accord (LR corner of their car), so the impact went right past the steel beam behind the bumper. Destroyed the bumper cover, styrofoam, airbox, headlight, and fender; the hood and upper radiator support needed some tweaking too. 01 Accord vs 92 Camry. I didn't even have my foot all the way off the clutch, I was probably doing 3-5 mph. If I'd caught them just a hair toward the drivers side on my car, I probably would have had a similar scratch on my car.
