I put a new N54 in my car had a injector spark plug and coil that were bad on the first start. Had to test 12 injectors from both my engines and get new plugs and coils I ended up with all index 5 and 8 injectors teflon wrapped them which is the best thing to do for those and they sit extra snug and are more reliable that way. had a extra index 12 in the mix which wildly not the way to go at all with just mixed with 5 and 8's. car runs super good right now wish yah luck too the most of us get to that part of owning some bimmers

Thank dude. I already swapped the ignition coils from the old engine and it started a lot better. But the 4th cylinder is still misfiring😂
