Asked by Dec 23, 2008 at 06:18 AM about the 2000 Pontiac Grand Prix GTP Coupe

Question type: Maintenance & Repair

i was driving my gtp and got on the throttle about 3/4 while it was boosting it felt like something gave out... now when i drive normal with light throttle its fine but when i try press it so the car will pull and or build boost through the charger it makes a fluttering sound and hesitates to go ive heard of couplers going bad and causing a similar but ive heard it does this noise at idle also my car does not it just hesitates and has this fluttering kind of bogging sound if anyone has had this problem or knows what might be the problem i would greatly appreciate i think its either the coupler,a tranny issue or some kind of seal in the supercharger no check engine lights are on or anything but it did just start happening so it could come on soon thanx MIKE

a check engine light finally came on and i went and got the code ran and it said misfire in cylinder 2 caused by either vaccum leaks ignition issue or coils and fuel i think a guy on you tube has a video of his car called diagnose me my car sounds and looks like it does the same thing ppl said alot of things were. but it ended being bad coils ive replaced the plugs today and the coil that runs the number 2 cylinder but its too slick and Icy here right now it still did it after the plugs. havent drove it since i put the coil in somethings making feel like its not gonna fix it either
