0171 & 0174 Codes I have a 53 3100 truck with a 03 5.3 4l60. I have about 450 miles on the conversion. Every time I drive it I get these codes. Sometimes it codes within 1 mile sometime 30 miles. The engine trans computer fuel pump and everything it needed from a 03 Avalanche that I drove and had no codes. I have sprayed starting fluid anywhere it could have a vacume leak. No difference in RPM. New tank fuel line and factory fuel filter. Anybody got a clue?
