Hi All, Going to try and finally resolve my issue. 1999 Box Base throws a CEL P1123-1125 every 600 miles or so. Engine Leaned out cause of rich mix. I've been just clearing it lately....car runs GREAT throughout. New Plugs/AOS/ MAF/Fuel Filter/Fuel Press Reg/Cleaned and checked output of all injectors/Air Filter/Cleaned TB and Plenum.
Only items not changed is purge valve for the charcoal canister and fuel pump. I believe my Fuel pressure tested at 3.3Bar Engine off and 3.1Bar at idle which I think is on the low side but still within specs. Any thoughts on fixing this?? Thanks V
