[Mad Series 2]

hey guys i know theres alot of threads on this but to sort through them all and some with different symptoms doesnt really help,

i have an r34 gtt series 2 owned for just over a yr and it started out as when i accelerate it seems like its missing de rating the engine then goes away when i rev hard

it only happens in low end of rev range i have 3" exhaust straight through blow off valve and pod filter other than that its 100% standard i replaced the coils sparkplugs and fuel filter

and the fault disappeared for about 2 weeks without faulting now its been 3 weeks and its started all over again i have done a resistance check over the harness for the coil packs

and not a fault to be found any help would me muchly appreciated

AFM. Clean and resolder. There are tutorials on how to do both. Fixes 90% of the fuely/ Sparky type problems. Do both and see how u go, and if not fixed look 4 other problems. Good luck
