I threw a P0101 while driving in 6th @ 81MPH. It say that it is a MAF or VAF
CKT RANGE/PERF MAF (LB/M) 1.42. I have a KnN Filter on my car with 47,800 miles. I'm thinking it is my MAF what do u tuners think?
Here is my freeze data.
P0101
ABSLT TPS (%) 24.3
ENGINE (RPM) 2273
CALC LOAD (%) 20.0
MAF (LB/M) 7.21
MAP ("HG) 23.0
COOLANT (F) 196
LT FTRM1 (%) 13.3
ST FTRM1 (%) -0.8
LT FTRM2 (%) 10.2
ST FTRM2 (%) -3.1
VEH SPEED (MPH) 81
FUEL SYS1 CLSD
FUEL SYS2 CLSD
Any help would be great, it runs like popo if u let off the gas in 6th then stomp on it, just starts to buck and sputter. only in 6th this happens.
Thanks

I have had the exact same trouble many times. 6th gear.1850 rpm at 80mph =stumble = PO101. With the stock Maf putting the screen back in stopped it and with a descreened recalibrated LS6 Maf, I had no screen to put in so I turned the Maf 90 degrees and the problem went away. I think the airflow does not flow even over the Maf wires with the screen removed. Rotating the Delphi 85mm Maf 90 degrees so the filiments were in a different place in the airflow just happened to work. Now PO101 has not come back and the car runs great. Hope this helps cause I have been fighting this for some time and found nothing wrong.

Did you just clean your K&N Air filter?

Take your MAF apart and clean it. Use Q-tips and rubbing alcohol. Be careful!!!

Maybe three months ago. I just cleaned it with carb cleaner, so far it works like champ. I still need to retune the car for 4.10.
Thanks.

if it was a bad maf the fuel trims would be maxed out

i would start at cleaning off all the maf stuff. LTFT look really high too they should be around 0%. whats the other codes definition? what are the idle fuel trims ?
