Thread: 06 GP GT Acceleration

I have a 2006 Grand Prix GT with 73k miles. Recent maintenance: trans fluid and filter change, supercharger oil change, coolant flush.

Every once in a blue moon (sometimes will happen immediately pulling out of a car wash, don't know if that has anything to do with it) I'll accelerate from a stop and I'll have to push on the gas harder than normal, and as it's accelerating I can feel it gradually gaining power. I can immediately stop and accelerate again and it'll accelerate normally. I have no idea where to start, and it's hard to diagnose because it's only done it a few times.

I believe it is in the fuel tank on the 06's.

If its the same fuel system as my 06 its in tank. And mine doesn't have the access panel. But u can make the access panel your self by cutting it in trunk. There a spot for it but they just didn't cut in

I'm about 98% sure the 04's were the last year to get the easy to replace fuel filter.

04-05 was the last years, 05 depends on build date.
