Did you check for vacuum leaks?Still chasing the P0171 (I am trying to do everything short of pulling the fuel injectors!) - replaced the upstream O2 sensors (Denso 234-4169).
Plan was to also replace the downstream O2 sensors but took one look at the state of nuts and decided it 19F is too freaking cold to deal with this. Anyone has any ideas how to deal with this without resorting to cutting and welding?
