E36 M44 Misfire!

318 M44 Engine.
There was oil in the spark plug chambers and was misfiring, so i did the valve cover gasket / spark plug seals. Its all sealed up properly now, with new spark plugs but still a misfire under load (around 3k). Runs better now tho.

I'm suspecting that there is oil on the HT leads causing it not to fire strong enough. Does run better every time i clean them, but still not 100%.

So basically, this isn't a question thread really, as I do have my problem figured out. More of a anyone out there near Mississauga have extra decent condition wires that I can use till Monday when i can get some...

Make sure to check your ignition module too, I thought my issue had to do with the plugs and wires, but I find my issue was resolved with the module, expensive to fix, but there is also a way to do a conversion to CoP (Coil on Plug). Takes some time to do, but it will also help in other areas.

Do you mean the ignition coil? Is there a way to test it? It seems to idle / drive fine now, but under load (>60% throttle), theres a hesitation. Almost like a "rev-limiter" type of bounce if under too much load.

I actually don't think its the wires anymore, leaning more towards clogged fuel filter?

Did some reading, could potentially be a bad crank sensor as well. Anyone ever have a similar issue?
