Hey guys
I got a 2002 GTP a couple months ago, and up until a couple weeks ago, it ran great! Then it started to sputter a little if I'd give it too much throttle. The engine light came on and I got a guy to scan it. It turned out cylinder 3 was misfiring. So just as a test I changed that plug. I can't do much at the moment because I have a broken wrist. Since this problem happened, I did the fuel filter, air filter, cleaned the MAF, ran some fuel line cleaner stuff, and changed the one plug. I have a set of plugs and wires coming from ZZP. I always run the highest octane fuel I can get. The only mod on the car that I can tell is the exhaust has been done.
After I changed the one plug, I did notice a difference and it ran a bit smoother, but still sputters when I'd give it some gas and it gets to around 30km/hr. Sometimes it smooths out again. The car also has much less power. Should I just see what the new plugs and wires do? Any other ideas?
