lets talk spark plugs.

i suppose my next move in my epic quest to get rid of my wot misfire is to change the plugs.. what is the best n/a 2v plug? i currently have tr55 ngks in there and they looked ok. i have all mods including cams in case anyone asks.. and i also just replaced the wires..

5 cel codes

4 codes for the rear 02sensors because of a ruined harness.
1 for the evap canister that i just replaced.

i really want to get to the bottom of this. they can be a locally picked up plug (autozone, orileys)

or if i have to order i dont care. help me out guys.

I have used almost every plug and always go back to the Ford Plugs. I use the 1 range cooler Motorcrafts.

NGKs are fine. Have you cleaned your MAF lately?

Nick at Modular Head Shop recommended ngk tr6 plugs for my setup. He said that the tr55 would cause the car to detonate :dontknow:

and with our cars being pratically the same with your ported heads and mine still being stock, maybe my spark is too hot and i need to step down to a colder plug..
