Re: resetting car computer
Its just a Reset problem. i had the same one. its nothing else. when the battery is disconnected from the car for a long period of time, this will occur. all you do is the idle relearn procedure and your fine. here is how you do it.
Idle relearn procedure:
On a lot of late 80 to mid 90 GM vehicle you have to relearn the idle if battery is disconnected or ECM replaced. First disconnect the battery for 2 minutes. Then start engine with all accesories turned off, and let idle in drive for 10 minutes (no cheating make sure it is a minimum of 10 minutes). Turn off vehicle for 1 minute. Restart and let idle in Drive for 5 minutes. if the RPM's fluctuate while idling you can slightly increase throttle to compensate but try not to use any throttle input. Hope this helps. we get a lot of this idle surge complaint after the owners changed the battery. It sound stupid but it works.
