Hello friends,

I have a 06 grand prix gt supercharged with 46k miles. It drives awesome, just that when i pedal to the medal, it doesnt GO like it should. the RPM stops at 3000 and goes up and down from 2800 or 3200 RPM. I can feel the engine not wanting to rev anymore and the check engine light turns on and blinks for about 5-10 times before it turns off.

I need help please!!!
