Have you changed the ignition leads? What was the condition/colour of the old plugs? Have you done a compression check? If it is sporadic that points to an electrical problem If you can get it on a diagnostic at a garage that will help pinpoint the reason but ignition leads should be checked/changed.Also the distributor cap and rotor arm should be inspected for. any obvious tracking/wear etc although sometimes substitution is the only way to pinpoint the problem.

regards
I hope I have been of help but please do not hesitate to ask if you have any further questions.

Missfire on cylinder 8 on bmw 545


move the ignition coil to another cylinder and see if the miss fire moves. If so replace that ignition coil. If the miss fire stays on that cylinder it is more likely the fuel injector. Was their carbon on the spark plugs when you removed them? This is indicative that the fuel injector is gummed up.

CHANGE FUEL FILTER AND CLEAN FUEL INJECTORS,CLOGGED FUEL INJECTORS WILL CAUSE ENGINE TO MISS, MAKE SURE SPARK PLUG GAP IS 0.060, LEAN MISFIRE FROM WEAK FUEL PUMP,CHECK FUEL PRESSURE SHOULD BE 40 - 50 PSI. IF EVEVY THING CHECK OUT OKAY,MISSING PROBLEM COULD BE LOW CYLINDER COMPRESSION OR INTAKE MANIFOLD AIR LEAKS.DO A COMPRESSION TEST IF NECESSARY.

It could be the fuel pump or the pump relay or fuse. It could be the fuel filter or the gas lines. If they all check out, it may be the fuel injectors. Start with the pump and make sure gas goes to the filter, through the filter, to the injectors. You'll find your problem.

The fuel system is a drive by wire and there is no accellerator cable.Check the plug going into the injector pump and clean,there is probably water here stopping the correct voltage to the throttle pump spool.
