Hi guys, has anyone had this problem before? My 260rs is stock as a rock at the moment, it has a missfire only on cyl 1.
Compression is perfect
I have replaced coils with new splitfire items
Tried known working sensors off a mates car, afm, tps, aac,cas
Changed injectors
Changed spark plugs
Changed ecu's r33 gtr & pfc could make it better with power fc but not right
Have checked everything for leaks or loose clamps ect
Could it be something with the harness? Or something simple?
An
