Hello all,

I've seen a few post regarding E85/Longtubes and them causing fouled out 02 plugs etc.
Didn't think it would happen to me but it may have happened.
2015 M6 5.0 18 Ported Mani (locked out) 47 lb injectors, JLT Intake, SP 1 7/8" Headers (not angled), e85 Tuned by PBD. The typical bolt ons.
Had all of this installed at my local shop about 4 months ago, I have had little to no problems until this morning.
Guessing maybe you all have had something something similar happen... Started the car up to a usual rougher start than a normal 93 car, (was told from PBD that it's likely because E is harder to start than 93) which is known, I may have to pat the gas every now and then to keep the car from dying at times, not all the time but most of the time it catches itself. Anywho, I am cruising to work and I get a CEL code. I pull into work and check the codes. To my surprise it has thrown 3 codes, 1 - PO151: 02 Sensor Circuit Low Voltage Bank 2 Sensor 1 ... 2- P115E: Throttle Actuator Control Throttle Body Air flow Trim at Max Limit.. 3: U0422 - Invalid Data Received from Body Control Module..

I have since emailed PBD, to see if this could potentially be tune related. Looking for a little insight on if any of you have received these codes, or have received them all simultaneously at all?

Sounds like a low voltage event. How old is your battery?

If you have forscan reset the bcm. If not unhook the neg battery cable and touch it to the positive for about 3 seconds.

Should cure it.
