 Engine Problems
I have a 94 3.8L 5spd, was running fine till about last weekend the check engine light came on. It started out with P0302 code (cylinder 2 misfire). i put some fuel injector cleaner in it thinking it was a injection issue. checked the code the next couple days, then P0301 (cylinder 1 misfire), P1132 (Lack of H02s11 switch sensor indicates rich), P1131 (Lack of H02s11 switch indicates Lean), P0171 (System to lean bank 1), P0172 (System to rich), and P1130 (fuel trim at limit)....
I've replaced plugs and wires, and fuel filter. coil checked out fine, i have correct fuel pressure. Anyone have any ideas? help is greatly appreciated |
