Asked by Tonya Mar 10, 2018 at 02:29 PM about the 2006 Pontiac Grand Prix Base

Question type: Maintenance & Repair

Ok so my car is a 2006 Pontiac Grand Prix
supercharged engine and a couple of days ago it
started acting like it had bad gas and was
sputtering really bad took it to autozone had them
run codes was a o2 sensor change it and then after
I changed it a day or so later I was headed out of
town and it died on me with it telling me I had
reduce engine power . Bought some mass air flow
sensor cleaner and that helped for a day and went
to go home and started it and it started right up but
died after a few seconds ran the codes on it and I
am getting p0172 p0068 and p0101 cleaned throttle
body and it ran for about a day and started it again

I don’t know if you figured it out yet man but I’m having the same problems with my 05 Grand Prix gtp. Got any advice? I’ve cleaned the throttle body, changed coils, changed maf like you did, I have an exhaust leak I believe but don’t think that would be the problem if it wasn’t yours.

My 05 GP GT, had a bad coil pack and one of new wire that had popped up on one coil pack and another not fully seated on a plug. Made it lag at slow accelerate and lag/serge when I floored it. Kinda like bad gas or clogged fuel filter.
