Okay. I was just reffered to this site from cardomain.com.
I have a 2002 grand prix gt, the 3.8 v6. Yeah!
Anywho. Maybe you guys can help me.
My car has been acting REALLY funny lately, and I don't know what's up with it..
Like everytime I accelerate, it doesn't want to go..It starts to freak out at 2000RPM's, And kind of like, jumps a bit.
I personally think it's the tranny. But I've been told it's just a clog in my filter or something. I don't facking know.
It's just acting really sluggish, and won't go how it used to. It kicks in after I get to about 50MPH..and sometimes it doesn't even do that!
If anyone can help me, that'd be SWEET!!! I can give you more info also on how it's acting if you like..That's just a general description.
PLease help, thanks!! =]!!!!

for one, Welcome, for two sounds like a plugged catalytic converter to me, If it is a plugged cat, a Pontiac dealership will replace for free

I've got Boost!! I've got only 1.5* KR left my poor L36 block.....

had this happen on a 99 GTP. Look at a scanner we saw the #4 cyclinder was misfiring. replaced the plug wires and all has been good for a few months.

It could be any number of things though, like the fuel filter mentioned above.

There's a few "simple" things you could do that the dealership would do before recommending any major service. As already mention, check spark plugs and wires, change the fuel filter, also consider changing tranmission fluid and filter. If you can't remember when any of this has done, then it's probably time!

No No No..... First off is the service engine soon light on? If its on go to your locak advance auto parts store autozone or napa anyone one of them will scan the car if the light is on and see what the code is. If its on have that done and report back here with the code and we'll have ya out man. Or pm me and I'll walk you through whats wrong with it if you have any engine codes..

if SES light is on...your able to have someone scan it.

however if it is not on..I am leaning toward a clogged Catalytic converter. as it is not allowing the exhaust gases to escape and pluging up your engne. how many miles do you have on your car?
