My 2000 Cherokee stated running rough a couple of times. Almost like not getting enough gas. Put in a bottle of Lucas injector cleaner and drove home. Ran good on the way home, exhaust tone seemed better, even seemed to run much smoother and have more power. As I pulled into my drive way my check engine light came on. Pulled the code P0171 only. Seeing as it has been ages since I replaced my plugs, I pulled them and replaced them. They where really in bad condition, couldn't even see the center electrode in some of them. Looked at the possible causes for a P0171 code, and other then injectors, it would seem most of the potential problem areas would affect both bank 1 & 2 and not just bank one. Please help this old man get his Jeep running right again.
