Engine Performance problem
2001 Pontiac Bonneville 6 cyl Front Wheel Drive Automatic 255500 miles
Why would the RPMS in my car start surging up and down while I am driving at normal driving speeds? It usually does this in the afternoon after about 15 or 20 minutes. When I come to a stop sign, I have to come to a complete stop and let the RPMS go completely down. The engine starts racing up and down and I can barely make it home. Please advise.
