Thread: 1997 grand prix tach quits

Well we just drove the car almost 600 miles. Averaging 29.5 mpg. The only issue that we still have is it wants to ,miss or stumble under acceleration. It doesn't seem to matter what rpm your currently at. You can go pretty smoothly and not have an issue , but say you have the cruise on and your starting up a hill the system will stumble under acceleration. I have this without cruise also.
