Engine Performance problem
1997 BMW 540i V8 Two Wheel Drive Automatic 151000 miles
I have this car that has misfire detection in cyl. 8 and I've changed the spark plugs, moved coils around, changed fuel and air filters, moved plugs around, cleaned electronic idler valve. Still getting misfire detection in cyl. 8 after resetting the codes with a OBD reader. Kind of lost here. Any ideas?
