Question about 2003 Chevrolet Silverado 1500
Also have a 2003 silverado 4x4 4.8l "v" engine. I currently have 2 codes 171 bank 1 runs too lean & 174 bank 2 runs too lean. my tech says it's the intake manifold? does this make sense?
Means that the O2 sensor has seen a condition of more air in the engine than it can supply fuel (there is only one bank on the zx2).... My guess is the PCV hose is broken ... Not remembering the motor in the zx2 right now hurts me.. but I've seen the break either on the valve cover gasket, or where it enters the intake (it sometimes is hidden underneath)
