I have a custom tune from TTFS. I've driven only 15 miles since i cleared the codes, but all the other monitors are ready except evap and O2. I'll keep driving it to see if I can get them to ready up and if the misfire happens again.

Default Re: At my wits end, misfire issue, OBDII monitors incomplete...

update for everyone, i didnt have time to swap O2's, and im pretty confident they are in the correct spot, so im going to try other items before swapping them willy nilly.

I have NOT had any misfires since replacing FPR and Filter, HOWEVER, Evap and O2 monitors are still showing incomplete. I have done 2-3 drive cycles over 50 miles...i may be doing the drive cycle incorrectly though, hence them not readying up?

I did take the car for a drive and these are the trims:

for trims, on cold start:
- Short term FT 1: -15.6
- Short term FT 2: -25.5

These numbers bounce around between -12 to -18 for FT1, and -17 to -29 on FT 2 while driving and warmed up (at operating temp for oil & coolant)

While driving, i was checking FT 2, it went anywhere from +4 to -26, When idling Hot, the Short term FT's are the same as when idling cold. Long term trims on both banks remain +1.6.

O2 sensors on all banks are running proper voltage going between 0.4 to .89 volts.

I think I may actually be able to hear a vacuum leak near the fuel rail, gonna get a smoke tester and smoke test this ***** out. Need one for the E36 as well, so worthy purchase.

I just changed spark plugs, and i noticed all of them have a little oil on the threads, the terminal and components are oil free. I did notice Cyl 4 & 6 coil packs had dirty connections on the inside where it meets the plug. I cleaned it out as best as I could. As for the plugs, its clear every cyl is running rich.

I did notice some weird fuel thing when revving to 4.5k (once at operating temp), not sure if this is normal or not, video shows what im talking about. Its a video of live data.

I noticed misfiring for maybe 10 sections after the car was started for 1 min.

short term Fuel trims are still rich

You need to refresh the coils, that thing in the picture looks fried.

All equal. Get from FCP euro and then have lifetime warranty and can replace for free.

Not sure about those specifically, but I know bigjae uses coils from 330 which are much cheaper than m3, maybe he can chime in.

I talked to the shop, and they think its a fuel pump.

I looked at my receipts and I bought my walbro off amazon from an unauthorized walbro seller, So i think my pump is fake, potentially giving fueling issues.

I bought the radium kit with a new walbro, will put that in once its here.
