my skyline has developed a missfire/hesitation from 4-5500rpm ..
mods are: 3inch, 10psi, Pod + CAI
i've done my research with this problem i.e spark plugs, running NGK coppers BKR6e 0.8 gap, which i replaced monday - problem still exists.
tried backing off boost to 8psi, taped Coil Packs - problem gone for a day even put boost back to 10psi - no problem. Decided to araldite them, put them back in and problem is back !! Even did night test with cover off - couldn't see sparks.
before i go out and buy splitfires, should i need to gap the plugs down to 0.7 ? but then i've read less spark = less power.
on the other hand .. could it be missfiring due to rich mixtures in which case an SAFC would solve the problem ?
i'd appreciate anyone comments.
