2004 Verona error codes P0171 and P0174 twice
I have a 2004 Verona that throws P0171 and P0174 twice on the code reader.
This is weird.
I know this to be the System is too lean on both banks.
I have gone thru the tremendous pain of replacing the gaskets on the intake manifold. And replacing the spark plugs (and looking at the fuel injectors - which i thought were the spark plugs).
What could cause these codes to show up twice on the code reader?
I am about to clean the Mass Intake sensor once i find it.
Any other ideas?
