Bad Misfire-Pulled 10 codes with Peake

[m3f_RotRedM3]

Ok guys, I need some help with this.



My 96 M3 is misfiring and not just a slightly inconvenient misfire. I cannot drive it the way it is running. I put in new plugs and moved coils around. Nothing changed.



I bought a Peake scan tool and it pulled 10 codes.



FC-EVAP Incorrect Purge Flow

FF-EVAP TEV Stuck Open

OA-Coolant Temp Sensor

F1-MIsfire, Cyl #4

F3-Misfire, Cyl #6

F0-Misfire, Cyl #3

F2-Misfire, Cyl #5

08-Air Mass Sensor

19-PreCat o2 sensor heater, Cyl #1-3

37-PreCar o2 sensor heater, Cyl #4-6



Do these point out anything obvious for you guys? Or is there one thing that would throw all of these codes?



I can fix just about anything but diagnosing the problem is not one of my best qualities



I need to get it running asap and any help would be greatly appreciated.



Thanks in advance

Fix this one first and check what remains after that.

By "moved coils around" you do mean jiggled right?

Would this be the purge valve that needs to be replaced?

Swapped coils to different cylinders.

Yes. It should close automatically, so maybe it's just mechanically jammed.

Is there a way to test or fix temporarily to see if it's the problem or just order one and replace?

[m3f_El Zilcho]

Not really. The DME opens and closes it, and registers the expected variations in the O2 readouts. If you can force it shut you will still get some codes, but maybe it would get rid of the misfire. I'd just replace it since it seems broken anyway.
