When it is cold out side my car always idles to high and now that it is hot(in Houston) it wants to die at every light once it gets warmed up. Any way to adjust the idle? From what I read on line there is an adjustment screw but I can't find it on my sidekick.
How about first checking engine temp to see if there is a problem with the thermostat, ECT, etc?? Idle is a symptom of another issue, and not the issue itself. 16v's bog with vacuum leaks once the car is warmed up, as well. You should give info about what the car does from first start up, idle, how it drops, etc. And also what maintenance you have done - tune up, timing, cleaning EGR, etc., etc.
I want to bring this back to the top because I am still having problems when I come to a stop sign or stop light. I have to turn off my A/C at every stop or the car will die. It is so funny because back in the winter when it was cold outside I had to turn on my A/C at every stop to keep it from idleing too high.
I hear you guys are say it is a symptom of something else but it runs fine when I am in motion and idles very good when I give it just enough gas to keep it running. I just wish I could adjust the idle up a tiny bit to keep it running at stops.
Actually, it dies when I come up to the stop. If I can keep it going as I come to the stop then it will idle fine while stopped. It is like the sudden let off of gas causes it to die.
Any other suggestion?
Car is getting to the 180 degrees it needs to to run correctly at speed.
The idle speed control is the sensor that controls the idle once the car is warmed up. Normally you would test it on the car by turning on the AC, or the heater and headlights, while idling, and see what the car does. The ISC is supposed to maintain idle (or raise it slightly with A/C on), when there is a load put on the engine. You can also test the ISC by pinching the air hose that runs from it to the air pipe off the air filter. When pinching this, your idle should drop. You can take the ISC off the car - if you shake it and it rattles, then it is no longer any good. You can clean it with carb cleaner as well - spray and pray.
There are other things that determine idle as well. Is your car timed and tuned properly? Is the throttle position sensor calibrated properly?
You advise that apparently your idle is somewhat temperature dependent. So, how have you determined that it is getting to 180 degrees???
