Help trouble shoot misfire
Hi,
I'm back using E85 after re-installing downpipes and intercooler due to dealer replaced my DME. I will be trouble shooting it tomorrow (swapping coils, spark plugs,...). But in the mid-time can anyone take a look at this short log for anything out of the ordinary? Background; Dealer replaced DME, 6 coils and 6 injectors. And I replaced all 6 spark plugs. Car had no misfire before using E85 (only 2 gal to half a gas tank). Misfire is on cylinder 3 Thanks.

After trouble shooting it comes up to two options;
- BMW Dealer didn't properly coded injector #3 - or the brand new injector is bad? swapped coils, then spark plugs, but misfire stays on cylinder #3. I just purchased the INPA usb cable to see if it is coded or not. But it does not get here until next week. Is is possible that a brand new injector is bad? I'm inclining more to think that the dealer did't coded it.
