    i have the exact problem i fixed my cadalitic converter and now are looking at my oxygen sensors but i really dont have any clue yet why this is happening, i know when you put fuel injector cleaner into the gas it improves a little and usually if you let the car warm up for 10 minutes before driving it wont do anything the drive is fine but dont let it warm up and its doing the exact same thing

You need to replace your IAC (idle air control valve). The IAC, like it sounds, control the idle of your car. When they go bad they will cause the low idle and stalling. The IAC is located on the throttle body and is usually held on with a couple of screws. It is an easy relatively cheap fix that you can take care of by yourself. Let me know if you have any more questions. Thanks for rating my response and for using FixYa!

Having trouble with engine killing or running rough even after it's warm.

not for sure but it could be your cam sensor. if the check engine light is on then take it to a parts store and they can run a scan and give you more information

Is there a kill switch on a 2004 oldsmobile alero 2.2L?

Probably not but it wouldn't be to difficult to install a kill switch depending on how you want it function. Two main ways that i would do this is 1 to kill just the fuel pump so the car will try to start with no luck of actually turning over or 2 on the ignition coil so the car will not try to start but auxiliary will be on. All that is needed is a decent on/off switch so basic soldering skills and a wiring diagram for your car =)

My 2002 Pontiac Montana has issues starting in hot weather. If it hasnt been driving for a while it starts and runs fine but the once you stop somewhere then theres a chance it wont start again. Actually...

check your temperature if it goes up quite fast you have a problem with your radiator or water pump, but if it is ok check your battery and alternator...

1998 Honda CRV stalls once it warms up then after

You need to replace your coil pack. It sounds to be over heating which results in no spark being sent and the enige dies. Very common fault and easily fixed.

My car kills when at idle. has low r/min at idle.

Check the Idle Air Ctrl (IAC) motor. It should allow air to bypass the throttle plate when starting and at idle. if it is not working it could cause veh. to stall.

The Symptoms tell me it is a head gasket. A leaky or bad head gasket would cause all of the problems that you mentioned.

Burning water causes White Smoke, Burning Oil causes Black Smoke. The oil and water are mixing with the gas in the cylinders and causing it to run bad. Pull out the dipstick and look at the oil on it. Does it look like good oil? Or does it look watery and or foamy or grey colored. Open up the radiator and look inside, do you see oil?

This seems almost text book to me... I would have someone local to you to have a look at it to be sure.

2002 Regal - Engine kills right after starting cold.

There are 3 things that cause this, 1st and most common is a dirty idle speed control valve, 2nd is carbon on the back of the intake valves, last but not least is the wrong octane of fuel, if it requires 89 Octane and 91 or 92 is used the engine will stall code.

To clean the dirty idle control valve follow this procedure:
Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) 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.

Killing problem on 1999 bonneville

well it seems to be an transmission problem. when you have it under load(in gear) there seems to be resistance that stalls the motor. the engine speed sensor sends a signal to the ecm(engine control module) this in turn sends a signal to the trans control module. from there the signal goes to a solenoid inside the trans the shifts the gears. somewhere in that circuit is the problem. you need to take it to a shop and have a scan done, this will isolate the problem. please rate this ..thanks
