Having a niggly problem with my s15 where I cant get over 6k rpm under load.
Car gets to around 6k then misfires/feels like it hitting limiter. It then wont rev up for a few seconds after.
Any ideas?
I've gapped plugs to 0.7mm, tried different coilpacks, checked for boost leaks etc.
Going to change fuel filter and see if that helps any.
Wondering if I may have to do the fuel pump wiring mod and run the pump direct from the battery via a relay? Car has walbro 255 pump.
Any help mucho appreciated.
