With lots of elbow grease and two jacks I was able to reinstall the exhausts correctly (I think). The previous codes regarding an exhaust leak are gone. But after letting it run, the STFT seems to have a lean condition and icarsoft MB II found two codes. P2043 and p2047 and from what I gather, these are not supposed be on a gas engine but for a diesel, so assuming the code reader is picking these for a reason (runs rough) anyone have experience with this? The fuel has been sitting for a year so I plan to siphon it out and order a new filter/pump assuming I am having bad gas issues unless someone can point me in the another direction.
