Need help Well I checked the spark plug in cylinder 7 a week ago cause it was missin i replaced it and it fixed it but couple days later it felt like it was missin again so i went to get the codes read and it said it was misfiring again in the same cylinder. Checked it again and the spark plug was white at the tip which means its hot...only thing I have are pacesetter coated long tube headers and a tsp x pipe. The plugs I have are ngk tr55.
None of my 02 sensors work either..I had got 2 new ones for the front and put em in and they still dont work :S and I still need to get some 02 sims for the rear.
Whats causin the problem???

One question for you, when you're driving. Are you hearing any detonation?

ok well I changed my header gasket and it still sounds like its leaking but its not from the header or anywhere else I checked...ever since I put those headers and x pipe on ive had nothin but problems with it now its tickin pretty bad sounds like a lifter cause I already checked all the rockers and everything else. I think im just gonna sell my car cause its a damn money pit.

You should have used the orginal GM gaskets when you installed your headers. Any chance you still have them? If so put them out and that will fix the whole leaking nose. Also, how long has it been since you insalled your headers, because sometimes you need to go back and tighten up the header bolts a few times untill they become seated correctly.
As for everything else... Sorry I cannot help

You don't have a leak at the headers anymore. What kind of clamps are you using on the rest of your exhaust? Particularly at the end of the headers?
im using the U bolt clamps at the end of the headers but I checked it and its not leaking and the rest of it is welded. Well I dont think this tick is usual cause its damn annoying and its louder then when I first had my headers on and everything was fine.
