Hey guys I'm new to the forum!

I have a 2003 EB 4.6L that keeps giving me the same OBD II Errors [P0171 & P0174 (system too lean on bank 1 & 2)]. It happens right after I put gas, I clear the codes and they come back after a few days.


Any suggestions?

I'd read that a PCV vacuum line hose/elbow needs to be replaced. Is this the same fix for my 2003 Expy? If so, does anyone know the correct part number? The one listed is for model yr 98-02



Thank you in advance!!

 

Only if that is what's causing the lean codes.

First pull the elbow off and closely inspect it to see if it is causing a vacuum leak.
