2002 Grand Prix Gt issues, need some expert advice

Just want to say hello first of all, this is my first post sorry its in here and not in the intro section but i need some serious help. I have an 02 GP GT and i have developed an issue when accelerating. The car jumps and studders real bad almost like its starveing for something. I thought it might be the O2 sensors so i replaced them both front and back. Then i thought maybe the catalytic converter, so i replaced that. Now the car is still doing the same thing and i am utterly clueless as to why. Any suggestions or comments are greatly appreciated in advance and i look forward to posting on here more.

Thanks

TJ
 


i hope u had a scanner hooked up and got pointed to the lean, rich, or misfire problems if you replaced both sensors and the cat, I have a 02 GP GT that went through that last year, ended up being a cat now its good, have you checked the fuel pressure regulator? do you have any codes now?
