My 04 has been having issues with hesitating under load, and occasionally throwing a code for misfire when I punch It. I thought it was fuel starvation, but when the fuel pump died and I replaced it, the problem remained. Then yesterday when I had been driving around town running errands, it got in it and it immediately went I to limp mode after startup. I now am thinking spark plugs. My main question is, are the NGK-TR6 good for my stock 04 GTP?
