Hello all. I just pulled my trouble codes from my 03 H2.
P0171 System to lean bank 1
P0174 System to lean bank 4
I will be doing more diagnostics today but is there a quick fix to these? A cronic problem others have had with these codes and first place to look?
Manual advises
the system will go lean if injector is not supplying enough fuel.
A lean condition could present during high fuel demand.
Posted this in another forum. Wondering if any techs in here
Any ideas? thanks in advance
