Question about 2000 Chevrolet Cavalier

1 Answer

Car stalls when idling at stop light

My car is peridically stalling when I go from driving to idle. It also runs very rough--almost like it is chugging right before it stalls. The car starts right back up again once it stalls. Also, in the past 2 months the check engine light has come on for a period of 1-2 days and then goes away for 2-3 weeks and then come back on again for 1-2 days etc. I have taken the car to a mechanic and he said he hooked it up to a computer to check the engine and it said everything was fine. Does anyone know what could be causing this? The car is obviously not functioning normally.

    Since the mechanic I went to seems to not have this, do places like autozone offer this scan or do you know of reputable "chain" stores / mechanics that do?

    So I went to autozone and we ran the engine diagnostics when the check
    engine light was on. It turns out the problem is a cylinder 3
    misfire. The worker at autozone told me that the gasoline might need
    techron to clean out any residual 'gunk'. So I am going to put Chevron
    Techron in the tank when I get down to 1/4 of a tank and see if that

Have checked the idle air control valve. If stuck closed it will not allow air to bypass the throttle therefore it will start and stall.

It sounds like the engine temp sensor is not right, but if that were true you should have a check engine light and a code for the sensor.
Have you checked fuel pressure ?

Here are a couple of guesses for things to check: vacuum leak (low vacuum pressure), worn distributor cap or rotor, incorrect timing, clogged fuel injectors, malfunctioning fuel pump (low fuel pressure), ignition module on its way out. I hope these suggestions help you out.

The van stalls without notice at times when ready

This sounds like a classic case of either a dirty/faulty IAC (Idle Air Control) motor or a sticking EGR valve. If you can prevent it from stalling by keeping your fot on the gas slightly and it always restarts right away and runs good when restarted, I'd suspect the IAC first. If it "chugs"when stopping and will run rough even with a little (not a lot) of gas pedal and/or it runs rough when restarted, I'd suspect the EGR.

Low idle

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
