My 2002 cavalier has about 75,000 miles on it. i noticed about a week ago that when my car is in gear when im stopped in traffic or when im rolling forward that the rpms seem to jump causing the car to jump forward as well. its mainly seems to happen when the A/C is on. also when the car is in park it only idles around 600 rpm and seems to have a slight sputter. if you can help out it would be very appreciated. thanks!
