I had some mods installed (dp, fmic,) and switched over to Cobb to try out their Sport flashes. Stage 1 Sport logged well, timing was good, boost was typical to other people. I switched to Stage 2+ Sport and logs were similar to Stage 1 Sport. This morning the car ran fine and this afternoon I get a CEL and limp mode with the following codes:
ECU:
P2FAC
P2EFE
P2F03
P2EE0
P2EF1

I searched the Google machine and came up with a few references to P2FAC and how spark plug gap was the issue. The rest of the codes came back with little information. I uninstalled Cobb V3 and the codes have cleared and the car runs fine.

I just wanted to get this info out there in case someone has the need to search for these codes. Cheers

Note: I only have access to 91 octane and is the reason for only trying the Sport flashes.

All these codes look like cat codes I think. Plug them into the search button here. Should get something.

The only reference I found was to this thread....

2FAC: Combustion miss, cylinder 5: Spark duration too short
2EFE: Random/Multiple Cylinder Misfire Detected
2F03: Cylinder 5 Misfire Detected
2EEO: Combustion misfiring, several cylinders: Fuel injection deactivation (2EE0, not 2EEO- )
2EF1: Combustion misfiring, cylinder 5: Fuel injection deactivation

I would first start looking at your plugs then coils, specifically CYL 5. Did you replace the plugs before installing the COBB? That would be the first thing I would do.

I replaced both coils and plugs along with the mods. Thanks for the code break down. Guess I am going to pull some plugs and check the gap.

[MacE90]

So I inspected all my plugs and found them to be properly gapped for use in a modified engine (0.022"). All spark plugs had carbon build up. Cylinder #5 had the most build up and I noticed the retaining clip on coil #5 to be loose. All plugs and coils only have 2k miles on them. I replaced all six plugs and will continue to use the same coils in order to evaluated their effectiveness. I did not notice a fuel smell on any plug. I hope this yields more information and solution!

I have the exact same codes on my N55 X5. I swapped the coil and spark plug from cylinder 1 but did not get anywhere.

The only thing i can figure is that the injector is bad? I dont know how likely bad fuel could be, but it happened shortly after a gas fill up.

Was this resolved I am having similiar codes? Is this a bad injector?

[MacE90]

Yes, injector 5 was leaking. Spark plug 5 had a very strong fuel smell.
