So I scammed my truck today, got two code0171 and p0174.
Did some research, found out some common possible cause:
Dirty maf sensor
Vacuum leak
Manifold intake sensor
But my fuel pump went bad and it was replaced 10 days ago.. Could a bad fuel pump caused the code? I had about 600miles on the new fuel pump.
My mpg is fine, about 20 on highway. Truck runs fine as well..I don't know if the mechanic reset the code after he replaced fuel pump, my guess is he didn't.
Does code disappear by itself after repair?
I know how to clean maf sensor but how do I check vacuum leaks?
