rb20 misfire

[s15_spec_r]

right lads, its starting to annoy me head, ive put a new afm, brand new grade 7 iridium plugs and nearly new splitfire coils into my r32 but its still misifreing

could the plug gap be causing it? i didnt check the gaps on the plugs i just lobbed them in. what should the gap be and how do i go about changing it?

cheers

wouldnt say its the gaps on the plugs , are the wires to the coilpacks ok and all wire in the plugs

What make are your plugs?

[s15_spec_r]

ngk iridium. twas bog standard ngks that came out of it so a colder grade plug can hardly make a shit of it, i used the same plugs on my s15 wihout any problem

gap should be about .7 for a skyline i think.......

Could be the gap. But could also be fueling... Ie pump or a dirty filter... Depending on what sort of misfire..

check your fuel pump!!!!! i think alans was doing the same thing and when he changed the fuel pump it was perfect!!!!
