Cause for misfiring unknown
 

2009 535i
misfire when given the right amount of gas. Car will remain misfiring until you let off the gas and ease back into it. If I stay into it while it's missing, the CEL will come on for approximately 30 seconds.

I've tried cleaning the fuel systems, replacing ignition coils, and spark plugs. No change in the missing. I don't know where to start in figuring this out. I'm at my wits end, please help!

Do you have a code reader? Is it throwing any codes? That's the first place to start. Otherwise you will just be throwing money and parts at it.

Unfortunately it's not storing any codes. Throwing money at it is what I plan to do. I think I'm gonna do the injectors now
