Chevy Express
Newbie
So I had a power performance issue with bucking, which got worse, finally threw a code for MAF out of range, and after watching Fuel trims LT+25, I pulled the sensor plug, and it restored all power and no bucking.
So i buy a new Delphi AF10057 MAF, install it, and now fuel trims are averaging -18 and it actually threw a bank 1 rich code. and it slightly stumbles now. This is on a 2000 454 express van cut off motorhome.
I am extremely confused as to how it can now swing completely the other way.
any thoughts.
