A misfire is usually a coil. Modern plugs rarely go bad in modern cars. It also could be a bad injector. These cars are notorious for losing coils. Try replacing them as a first step.

Better yet, get the fault codes read then you'll know what's actually causing the misfire, instead of guessing...

I do have an dormant E92 328XI I'm no longer using (pending trade) could I pull the coils off that car and swap them onto banks 2 & 4?
Thanks for the feedback!! -stink |

FYI...
Cheapy scanner (autozone) Detected misfire on cylinder 2 and 4. I do have those suspected coils out and they actually look fairly new. Anything out the ordinary I'm supposed to look for on bad coils? |

So according to ECS tuning the 328 and 335 share the same MFG# from BOSCH.
Bosch 2550226 Mfg#: 12137594937. Just confirmed the coil packs from my 335 are indeed ending 7594937. |
