HI i was woundering if anyone knew why my skyline would miss fire and hold back with a front mounted intercooler put on it ??

3 most likely suspects are.....loose hose to front mount, spark plugs or coil packs. Check in that order.

[Gambit]

Holding back with a front mount and increased boost is most likely to be overfuelling.

Misfiring will probably be down to coilpacks or plugs.

Quite a common prob.. mucho info on this forum about these probs

Sounds like a hose off or overboosting.
