Back To Stock??spark Plug Help!!!
Back To Stock??spark Plug Help!!! ok here is the story. i just recently changed my car back to stock i had an sts turbo on it.(check sig below for details on turbo) i had to sell it because i needed the money. i was running ngk tr6 one step colder than stock @ .35. is there any advantage to leaving those plugs in at that gap or should i replace them with proper heat range and gap. the car is back to stock except air lid, exhaust and custom ported maf and tb. they are still in the car, and it seems to run just fine. so leave them in or change them out?
thank you
thank you
well thats what i thought but know after only a few days of running it this way i get a p0420 code that popped up last night. so i didnt know if the plugs had anything to do with it or not. but i erased it and just wait and see if it comes up again. never had a problem when the trbo was on. well thanks for the input.
