Engine Performance problem
2001 Pontiac Grand Am 6 cyl Wheel Drive Type unknown Automatic 78000 miles
----------------------------------------------------------------
I recently had the head gasket replaced. A few days later, I noticed a little hesitation when trying to go up a hill. When I started my car the next morning, the engine was very rough. Once the car is warmed up, the rough engine stops. However, the hesitation when going up a hill remains (but not every time).
When the hesitiation is there, my "Service Engine Soon" light will flash until I am no longer on the hill. I put some fuel injector cleaner in my tank a few days ago. My car ran much better, and the hesitation isn't as frequent...but it is still there. Does anyone have an idea?
