This can be done without a computer hook-up and heres how!
Start the vehicle and put in drive, then set the e-brake( if the e-brake is frozen or inoperative put the front bumper against something that wont move or block the wheels very well ), then let the car run for 5 minutes in drive, shut the engine off for 5 min and repeat,, letting the engine run for 5 more min in drive, shut the engine off and you are done. ... the idle air control motor will have learned its idle map strategy at this point|||Nope. It may need to relearn it%26#039;s values since it was reset but it does that by itself. If it keeps up you have other problems.|||Well you clearly had the battery unhooked. That was a smart move. I still see people who try to change a starter motor without unhooking the battery. They are braver than me
Unfortunately when the battery is unhooked any length of time on your Lumina, the PCM loses it%26#039;s operating strategy and must relearn it.
Unhook the battery again for about 10 minutes. Reconnect and restart it and do not touch the throttle even if it sounds like it is going to die. You may have to make 2 or 3 restarts before the idle stablilizes. Let it idle for about 2 minutes once it establishes a good idle. Then you may proceed to drive it. Resist the temptation to feather the throttle if it feels like it is going to die. Let it die if it feels like it is going to. Restart it again and take off.
Basically what you are doing is letting the Throttle Position sensor get in synch with other sensors and the PCM.|||This car requires an %26quot;idle learn%26quot; procedure. Go to
www.w-body.com and in thier forum the FAQ has the procedure listed for the %26quot;do it yourselfer%26quot;|||no it will automatically reclear its self ,it may take a few times of driving it for this to happen ,but usually it will do it in a few miles of driving,or a few good restarts,if it doesnt have the computer scanned at auto zone and see if any trouble codes come up on it,the do this for free,this way it wont cost you for a diagnoses,those will usually clear up in a few miles of driving though,good luck on it.
