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
give us a little background info.
How many miles???
Any mods including air filter??
Any codes in the past other then the P1123-P1125???
Do you have an OBDII scanner such as a Durametric????
Do you have a way to get the freeze frame info related to the codes???
Do you have a vacuum gauge????Or access to one???
