I have a 2002 Grand am V6, 66,000miles. For 4+ months, it has had hesitation (pushing on gas pedal does nothing until it's almost floored), poor acceleration, choppy acceleration at high end of RPM, lower than usual gas mileage, and sounds like the engine is stressed. A month ago my tranny started clunking after long drives, or during hot, humid weather. Since then, Ii has had 2 tune-ups (replaced spark-plugs and wires), and re-built tranny. It still has all the symptoms as before except the clunking in the tranny. The check engine light will go on and off randomly as the car is stressed. I'm thinking a bad catalytic converter, the dealer already checked the O2 sensor and fuel lines and said they were fine. Any suggestions before I take it back so the dealer can "FIX" my car again?
have the same problem?
