My car passed last Aug. when I bought my car with no problems. The car had all the oragnial equpment on the car. Sence I bought the car. I had to replaced the Mas air flow censer. Bought a rebilt unit. Did the whole spring cleanning thing. Replaced all the vacume lines. Replaced the fuel pump with the orgnial GM unit. Put a stock replacment K&N air cleaner on and replaced the down pipe with a manderal bent 2 1/2 unit and a high flow cat. Thats all I have done to the car.
Its time to smog the car agian. The problem I'm having is when I set to long at a stop light or ideling. It starts to idle ruff and the service engine soon light comes on. If I rev the motor up it clears up and the light will go off. Or when I start driving the car it will clear up. Basicly it starts to load up a little. It dosent do it all the time just once in a wile. All the vacume lines are in place. I know it will fail if I take it in without fixing this problem. I don't have a scan tool. So I need some sugjestions, Please. Thank you.
