2009 BMW 335XI
So recently I've been trying to diagnose my misfire on my N54, I have swapped coils, spark plugs, injectors, changed injector seals, decouplers. My car is still misfiring at idle and under 100% load for some reason and I don't know what to change or what to swap anymore. If...

A little back story, at the tail end of 2019 my car went down with a bad HPFP. As the car was already down and I'd have take it apart, I decided I'd install my mods and maintenance parts I'd been gathering. The misfire started pretty much after...
Well my cylinder 2 electrical problems have returned. :coldsweat:
It started a few months ago. Started to get 2E19 DME Firing Cyl 2, especially after the engine had completely warmed up and idling or driving slowly in a parking lot or garage.

I'm running the precision ignition system on e50 and usually 17-20psi. I had been using NGK 95770 gapped to .022 which worked fine for a while but I started getting random misfires under...
Hey guys I just installed the Precision Ignition upgrade on my car. I'm super happy with how the car feels now. I was getting crazy misfires before and somewhat of a rough idle but it runs mint now! I'm also working with EMP tuning so I can get the most power out of it.
I made a DIY with some...
