RESET PCM

2001 Pontiac Bonneville • 6 cylinder FWD Automatic • 149,000 miles

I just replaced the map sensor and was wondering how to reset the pcm to relearn the map sensor. The car still has a rough idle and reverse and initial takeoff

It will eventually adapt itself or you can disconnect the battery for 10 minutes but that will cause it to lose all the radio presets too.
