This is now really starting to piss me off!
90% under all conditions I'm getting a misfire when climbing the Rev range. No matter if I'm at part /full throttle!
I've so far changed:
Map sensor
All the coil packs
Cam sensor
Fuel pump
Alternator is putting out the correct voltage
Tps
Haven't done the spark plugs yet, which I might do tonight.
Now I wondering if the reground cams are causing this issue and the map on the standard ecu is throwing a wobbler!?
I also reterminated all the earth and positive cables to eliminate that as well.
Any ideas anyone?
What would cause it to misfire at exactly just under 4k?
