Did you change the fuel filter? Have the codes scanned they will tell you what's wrong with the car. Autozone does it for free.

I had it scanned already. But i didnt change the fuel filter. I will be trying that THANK YOU FOR RESPONDING

What where the codes? Ok on the filter. No problem on responding. Its what we're here for. LOL

Lol. The codes were P0135,P1646,P0135,P0102,P0141, &P1676

The p0135 codes are O2 sensors. The p1646 code is low boost from your supercharger. The p1012 code is a faulty rocker arm control solenoid. The p0141 code is O2 sensor heater circuit malfunction (bank 1 sensor 2). And p1676 is a EVAP code. You have a lot wrong with your car. Have it looked at by a REPUTABLE mechanic.

Ok thank you.

No problem and good luck! Hope its something simple.

My pontiac is doing the same the codes were 0304 0305 0302 the check engine light was on then went away. The car had stop when I shift into gear or stalled. What is the issue

Givan your codes are easy. They are all misfire codes. You need a tune up. Get new ac/delco plugs, good plug wires, and don't forget the air, cabin and fuel filters. Clean the terminals(were the plig wires go) on all 6 coil packs with emery cloth or lightly with fine (300-400 grit) sand paper. If the car still misses then its probably going to be coil packs.
