Hey everybody!
I have a 2001 Grand Prix SE with a 3100 in it. The car has 135k miles on it. For the last 10k miles or so the rmps have started to jump when either the gas pedal is released or the cruise control is disengaged. It is much more drastic when the cruise control is disengaged. Usually the RPMS rapidly jump somewhere between 200-1000 rpms in a split second before going back down to what they should be at. This is happens much less drastically when releasing the gas pedal, but still happens. On top of this the car has other problems including a knock and a pressure control solenoid that is malfunctioning in the transmission. I was wondering if anyone had any ideas to what could be causing the problem
Thanks for any input!
