Ey, jus trying to filter out reasons to why my cars runnin terrible.
My car had/has a missfire at the moment, so I've replaced the first few common causes of missfires (new splitfires and new AFM). When i originaly replaced the splitfires I was told to run the colder plugs the: NGK PFR6G-11's i re-gapped em down to 0.8mm and it seemed to fix the problem. A few days later i noticed it missfired when it was cold and since then its got more constant, Cold or warm. Since then I've replaced the AFM and it's still running poorly. Just curios to if any/everyone else put the colder plugs in when upgrading coils to splitfires and if that could be the reason its running bad still, or possibly any other ideas to why its still runnin like a bucket, injectors possibly or something fuel related? I had a bit of a search around the forum for other related posts but most sayin the same thing. coils or AFM.
any help muchly appreciated, Cheers
Brock
