2004 Pontiac Grand Prix GTP



Something to budget for definitely....I practically gave my torquestars away($100 with 7k on not so great allseasons).
Dude met me at walmart and said 'these should work great on a Cavalier'....I was like ahhh sure

What I meant by the Onstar deal was that it is a possible water leak spot.
If you have headliner staining or actual water in the dome lights after a driving rain or car wash thats it.
I don't remember how many miles are on your car. Maybe the previous owners caught it.
It is another simple fix.
 


Kinda bummed with my mpg! 😢

It is a GP after all not exactly what you consider a fuel efficient vehicle by today's standards. That's average.

That's the same or better than i ever got stock. Best i ever averaged before mods was like 23mpg at about 70ish. Consider yourself normal and carry on.
 


well then dont complain lol.
you can do some exhaust mods to help, headers etc. then get a tune, that would help in mpg as long as you keep your foot out of the gas.
for now all i can suggest if keeping your rpms @2500 or lower while accelerating to cruise.
