Hi Everyone, My 2005 GTP keeps holding back 95% of the time.The other 5% it runs like a rocket. This started with #3 cyl.misfire code. I changed all the plugs and wires and it ran great for several weeks but now it back to its old self without any codes.Also the fuel pump was changed by dealer before for same problem.Any thoughts ???

Any other codes?
03-02-2013
no codes ,but I did have a problem of #3 cyl spark plug had to be replaced 3 times in a two week s because they cracked

Hmmm. That's not a good sign for that same plug to crack repeatedly. Have you tried unplugging the maf? To see if its a difference in performance?
03-02-2013
no I'll try that tomorrow

Keep us posted.

Hold up on unplugging the MAF.
It would be alot more helpful to tell us when and where its not performing well.
Is the car driving normal under normal daily use and bog down on you when you try to have some fun and get on it or is the problem all the time, even during normal conditions.
Also what plugs did you use?

The miss and hesitation is under normal everyday driving .The plugs are A C Delco Iridium #41-101. and the wires were A C Delco.
