Hi
I have just brought an R32 gts-t with RB20det
After a while it developed a misfire, i pulled the plugs and noticed #6 was totally black while the others where white/grey like they should be
So i did the following things
- Test coil packs and swap them around
- Replace coil pack loom
- Compression test 158-163 across all cylinder s
- replace spark plugs
....but it continued to foul #6 after a while, people would look at the fouled plug and tell me its fouled by fuel
so then i
- had injector cleaned and flow tested (thinking injector #6 was dribbling, it tested fine)
- leak down test on #6 cylinder which got 85%
....but it still fouls continually #6, runs better with nice clean injectors but still fouls #6 and develops a misfire ?
when i come back from a drive remove #6 plug to check it i look down the spark plug hole and the piston looks very wet
Anyone have any ideas ???
Maybe an ECU fault ?
