Ok been trying to figure this out. My fuel trims at idle long term is -14 then I barely touch the gas and it goes to 0 then while crusing it goes to -3, full throttle pull it hits between 3 and -3 have lost a some power but does hit rev limiter. Tried diconnecting the evap line and capped the tb connection, no fuel at the pressure reg.,tune up and tb cleaned about 5 k ago, at idle o2 goes from around 800mv and drops to around 100mv then back but on a full throttle pull it goes 300mv to 700mv, the truck is all stock drivetrain this is with a tech2 scanner already reflashed with the latest calibration. Any help please !!!!!!
