Fault Codes P0171 & P0174:
We recently started getting an SES light for lean bank 1 and 2. Friday night I decided to take off the intake and engine covers to inspect everything.
I cleaned the MAF sensor and intake box first and noticed nothing unusual. When I pulled off the beauty cover and cabin filter housing I noticed the broken PCV hose near the firewall.
I re-attached the hose with gorilla tape as a temporary solution to isolate the issue. Drove the wagon to work yesterday and no SES light.
Going to order replacement hoses and may try and tackle the DISA intake manifold upgrade while in there. It looks like the local Pick-A-Part has a few different donor options for me to choose from. I'll update once I have all the parts lined up to swap over.
