I too need help. I have a 98 grand prix with the 3.1 engine. I also have flucuating RPMS at idle it will just start to jump around (search). I have done pretty much everything. Changed IAC today. that was 71 dollars. I have cleaned the intake and still no change. I am in desperate need to fix this because I am selling this car because i purchased another vehicle. When I purchased this car 2 years ago it started doing the same thing. 02 sensors were replace, and now because of the cold weather in winnipeg, I am faced with the same problem. Please help..
