Stock motor, Kooks LTs, custom tune, ported throttle body, 85mm MAF, MSD spark wires. Grounds are all clean.

Problem: Going about 70-80mph in 6th, maintaining speed with my foot on the throttle, The car will randomly bog and throw a p0101. She'll be fine for the rest of the trip.

2 weeks ago we plugged it into a Verus and did a test-drive. Seemed my MAF was a-ok, but MAP sensor was dropping out. We replaced the MAP and checked the harness, harness looked fine. Problem went away until today, it bogged again and threw the p0101.

My o2s have been throwing me codes too, p0135 is currently in my computer.

Does anyone have an idea of what this is, if its not MAF or MAP?

 

Any help? Any minor incline it will bog when maintaining about 85mph. There's no way I could go back to the future.

 

This code is about the MAF disagreeing with the speed
density airflow by too much. There is some stuff for
fixing this in HPTuners by monkeying the range. But of
course the real right answer is for the two airflows to
agree (and both be right, better yet).

 

ever figure this out?

 

try swapping in a new MAF the values may look ok on a verus but the PCM can be rather picky

 

Did you check out the freeze frame data?
