well i put my fully built motor in, and hooked up the wide band, and hooked up the power fc. the cams i have are very lopey, but i can hear a slight misfire at idle and when i rev it. but the wide band read that i was running between 10.5 and 11.5 afr at idle.

fuel pressure is at 44 psi, and injectors are pulsing. i can hear them pulsing and i the idle gets worse if i dissconnect each plug one at a time

does it matter if the coolant hoses on the aac valve are switched?

is there a was to see the percentage of output from the aac valve on the commander?

what about tps voltage on commander?

i just cant figure out why it is running so rich. if any one can give , me any leads i would greatly appresciate it.
