Engine Performance problem
1999 Lincoln Town Car 4 cyl Two Wheel Drive Automatic 162000 miles
I had a intake manifold put on, after that my alternator went bad after it was fixed. That was in June of 07. I just had to get the alternator replaced again. Since the intake manifold was replaced, the check engine light has been on. The gas pedal is hard and the car barely picks up speed. Can you please tell me what the problem is?
