P0102 Limp Mode at the Track (Video Included)
Threw P0102 for the second track day in a row today. I replaced the MAF after the first incident. It happened each session after 3-5 laps of hard driving.
Anybody deal with this before?
Details:
Power: 252whp
Intake: Velocity Stack
Exhaust: Headers + downpipes
New MAF sensor and housing
5w40 synthetic oil
PCV delete

Have you inspected the wires/connection?
Is the unit OEM? Aftermarket? If aftermarket by who?
If you can get your hands on a working ECU maybe try that as well to eliminate the possibility of that.

Forgot to add: I have a 350evo Bored Throttle Body
Could that be throwing things off?

SOLVED
Found the issue. It was a shortage in my MAF wiring from the MAF plug to ECU. The shortage was where the wiring goes through the firewall to the ECU.
