[QUOTE="Pharbach, post: 1046848, member: 77675"] Dillard, I've been overdosing the gas with LUCAS Injector cleaner and fuel conditioner for the past several weeks for the initial misfire issue (without the bank lean issue), as a clogged/dirty injector or rail could have been the culprit. The misfire seems to be intermittent now, so an audible test of injector may prove to be a false positive. Someone else suggested replacing the PCV valve and the fuel filter. He said the full rail pressure I had stated (38-42) was a little low and suggested replacing fuel filter. He also suspected a manifold leak near the EGR valve on the rear of the manifold and suggested a smoke test. My first order of business is to replace the PCV valve and check its lines for cracks, then replace fuel filter, then the #2 injector. Learned to go from easiest to hardest... What do you think?
