Not if you get a quality one like 3M installed by someone who knows what they're doing. Usually they cover entire panels so that there's no edge for dirt to get under.

Not specifically painting, but dent and scratch repair. You could probably ask any pertinent questions there, unless you're talking about whole hog booth spraying on your own.

I was going to be in the UK for the day (July 14th or so) due to a 24 hour layover I am allegedly going to have, and wondered about automotive attractions that might be interesting to check out. I'm coming into Heathrow and I guess I'd be taking the tube into central London where I'd stay for the night (I am still figuring this part out).

I guess I am looking for some kind of cool British Superbike race or a motoring museum or whatever. Maybe even some kind of car show in the area? Though I guess none of this really has to be in London. It could be farther away if time permits.

Brands Hatch have a British Formula 3 and GT sportscars race meet that weekend. I think Heathrow is pretty close to the Thruxton track aswell but I dunno if they have anything on that weekend.

alright so one of the nuts on my car is different


now the car came with a key but i had the brakes done a couple weeks ago and i guess the mechanic didnt put it back in the car. he said he mailed it to me (a week ago). now i need to go on a roadtrip maybe tonight or tomorrow morning and i need to be able to change my tires if need be.

now is there any way to get that thing off without using some super special awesome tool or breaking it off?

For an emergency? Take a ratchet with you, a hammer, and a cheap socket just slightly smaller than the nut in question. Hammer the socket over the locking nut and take it off. The nut itself may or may not be ruined, but you'll be fine with 4 lug nuts long enough to buy a new one at a Walmart or AutoZone.

Well turns out replacing a carb is pretty easy once you realize some parts from the old carb need to be transfered to the new one. I think I sat there for a half hour trying to get that brake booster line into the back of the carb without the screw in inlet from the old one. Anyway another question..

The Chevelle seems to get stuck at high idle, say I'm driving down the highway and I'm coming up to a stop. Now if I just get off the gas and start braking I have to get on them fairly hard as its idling retard high and will cruise at 35 with my foot off the gas. So, what I've been doing is tapping the gas when coming up to stops to kick it down to idle. I have to do this before shutting the car off as well otherwise it'll sit there and diesel as its reving so high. I'm not really sure what is causing it exactly, is the gas pedal itself gunked up or something? the springs that compress the throttle once you get off of it? although they seem fine, can you even buy new throttle springs from a parts store?

Open the hood while it's idling high and take a look at the throttle actuator to see if it's closing all the way.

I failed my emissions test yesterday (I knew this was coming, check engine light's been on forever and apparently they've gotten stricter with the OBD stuff).

1998 Honda Accord LX 4dr/4cyl. My code is P0420 - Catalyst System Efficiency Below Threshold (Bank 1).

What are the things that could be causing this that won't involve having to replace the catalytic converter? The guy who did the emissions test said it might just be a bad oxygen sensor, but looking around online it looks like a lot of people with this problem had to get their whole catalytic converter replaced. And sometimes more, if there was another part malfunctioing which is what killed the cc.

Since I have to get this fixed to use my car, I'm in a perfect spot to get taken advantage of by a mechanic, and I don't have a mechanic that I trust here in VA since I've only had one real trip to the shop since moving here. I also don't know anyone with a Honda who would be a useful source for a recommendation. Basically I'm looking for anything I should have them check before authorizing them to replace the freaking expensive catalytic converter.

I have a 2000 Toyota Celica and recently when I was driving I had to brake suddenly for an exit and the oil light came on. About a half second later it turned off and nothing seemed wrong. It did that again about 5 minutes later when I was braking, and after flashing for a moment it turned off. After an hour and a half more of driving there were no problems and this hasn't occured since. What would possibly cause this and is it worth bringing the car to a mechanic to check out?

Sorry, it was the oil pressure. I didn't get a chance to check the oil level because the event happened this evening and I don't want to hang outside in my sketchy city late at night if I can avoid it. The oil was changed less than two months ago, so hopefully it isn't low on oil.

I'd bet that your oil is low. When you braked, it sloshed away from the pickup, and so the oil pump was starved for half a second. No oil for the oil pump means no oil pressure, and the light comes on.

It's normal for engines to start burning a little bit of oil between changes, especially as they age. Plus, it's possible that whoever changed your oil didn't get the drain bolt or filter torqued quite enough or something, enough to leak a drop every once in a while.

I have the same car but made a year later. I also had the same code a while back, but it was only a matter of taking off the gas cap and putting it back on. While researching it on the internet, I too found that the main culprits were the catalytic converter and the rear oxygen sensor. Basically, as I understand it, the rear oxygen sensor's job is to tell if the catalytic converter is doing its job. If either one of them fails, the ECU gets erratic numbers but doesn't know whom to blame. You may be able to have them read real-time data from the ECU while the car is running to see if the sensor is behaving erratically. Other than that, I think you might just have to bite the bullet and have the part(s) replaced.

I saw a lot of cheap (less than $200) catalytic converters on various auto parts sites, but I have no idea how good any of them are. It also doesn't seem to be too hard to replace one if you're inclined to do such things. How much are they wanting to charge you? Have you asked a dealership how much they charge for comparison?

My question:
My sun visors are quite loose, especially when moved all the way to the doors. This means that they swing about and hit me in the face even on fairly gentle turns. I took one out to try to tighten it, but there's really nothing to tighten. The friction to stop the visor from swinging around is caused by a spring pushing two parts together, and I can't reasonably get at and replace the spring. Is there anything I can spray in there to safely "gum up" the joint? I'm basically looking for the opposite of grease/WD40/silicone spray.

I believe it was around $800 to have a dealer replace the catalytic converter. Haven't asked an independent place yet. I'm pretty sure I have no ability to replace the part myself, but maybe buying it online and having someone install it would be a good compromise. If its not the greatest part in the world thats okay, I don't play on holding on to this car for more than another 6 months to a year, but I do need it to pass emissions to register it, and still be passing emissions whenever I get around to selling it.

Yea, those springs that bring the throttle back to idle when you let go of the gas don't bring it back all the way. What are these called? I searched autozone for "throttle actuator" and nothing came up.

Throttle return spring.

The sway bar is basically a long metal tube, and at each end it has a 90-degree turn and a short length, to make a [ shape. The two short ends of the bar are connected to the suspension on their sides. The middle of the bar is held by bushings so that it can rotate (moving both sides up or both sides down), but not tilt (moving one side up and the other side down). When both sides of the suspension are moving equally, the bar rotates in its bushings and nothing unusual happens. But when the car's weight shifts to the outside of a corner, the outside suspension tries to compress more than the inside. Because the bar can't tilt, the only way to move like that is to twist the bar. The energy required to twist the bar is effectively like having a heavier spring rate on the outside.

When you're in the city, you're starting and stopping pretty regularly. Acceleration uses up a lot more fuel than just keeping at a single speed. When you are cruising on the highway, for the most part all you have to do is overcome aerodynamic resistance - not a huge problem at 60 or 70 mph. On the other hand, every time you accelerate, you've got to overcome more than one ton of inertia to get moving.

Nah nothing complex here. Should be straight forward.

Car is idling a little rough at a stoplight. Most of the time it's fine, but occasionally it'll try to die and gurgle a bit, so I'll punch it out of it. Acceleration can also be a little bit sputtery. I would assume that's a plug/wires thing, right? Any other ideas what could cause that? Car's fine otherwise.

Part 2, depending on the diagnosis, how important is it to take it in? I'm thinking that as long as I'm not standing on it 24/7 that the occasional misfire isn't a huge deal, but could it become a bigger problem if left unchecked? I'm not in a hurry to get this fixed unless I need to be.

I'm no expert, but it might also be something like an airflow sensor or o2 sensor malfunctioning and screwing with the fuel/air mixture. Spark plugs are really cheap though, and you can replace them quite easily. Supposedly they should be replaced every 30k miles anyway.

On my beater, I need to do version 1 to even get it into some gears - once I blip, the gear will go in.

I have a semi-related question: I don't really have the room to twist my right foot anti-clockwise to do heel-toeing (it just causes my right knee to hit the left and feel far too awkward), so I have my heel on the brake and ball of foot on the accelerator. Is there really anything wrong with this?

In my beater I can do this fine, haven't tried this in my new (to me) MX-5 yet (the clutch is much further right than in my older car) so I'm wondering how to do it. Maybe I need to look into some screw-on pedal overlay things?

And if it's in the tread but you've driven on a flat tire long enough to damage the sidewall, you'll also need a new tire. If the tire is not completely flat, drive on a spare tire to the tire store and they should be able to fit it.

Most likely a loose belt. With the engine off, apply pressure with your hand to the flat surface of the belts on the front of the engine. They should be fairly taut and not deflect more than perhaps 1/2".

Yes. For proper control, you want to have your toe on the more sensitive input - on most cars, this is the brakes. Try using the side of your foot, rather than your heel, for the throttle. I wear size 13 shoes and have no trouble doing this in my NA MX-5.

By rolling your heel, you should be able to do this without a great deal of motion of your leg. My right knee doesn't move more than an inch when heel-toeing.

I always go with number 2. As far as I'm concerned, number 1 is a waste of time and effort. I'd only ever use 1 if I wanted to keep it out of gear for several seconds for some odd reason, and even then I'd engage the right gear before blipping to make sure I could get the timing right. Basically, under normal circumstances, I see no need to pause in neutral. Heeltoeing demands that the entire process be fast, so that's a definite number 2 situation.

Edit: taken out of context, this could make for some decent potty humor.
