    Talking At last no more missfire

    For a while my coupe was playing up (missfire, Boost problems). First i changed the bcs and it made a big improvement on the boost side well apart from the missfire. Then today i was looking at all the options that most other people on here has done and found one solution that has worked like a treat and that was to gap the spark plugs to 0.67 on my denso ik20. Now i would of gone and brought a few items like coil pack,afm,new set of ik20s,o2 sensor. The reason i didnt is because i didnt get no eml on or any codes stored so tried the gap solution and WOW what a diffrence it has made, feels like i have had my car mapped again.
    Any one that is getting the same problem i wld try this first.

    i thought IK20s were for relatively standard maps?

    Seeing as ur at Stage 3 id have thought IK24s were more suitable

    Im still on std map but using 24s gapped to 0.7 - nothing bad to report here.

    glad ur sorted at last though

    i have always recommended setting the gap to 0.67mm and its 9/10 times it cures a missfire on the zlet! i had all the issues you have had! trying this and that, and something as simple as a plug gap is the cause! like you have said its the first thing id do if anyone is suffering a missfire! glad your all sorted now matey!!!!
