Hi again,
Ok, so I have continued to resolve my error code 123 (check engine light on) to no positive results. My jeep continues to "hesitate" during exceleration, like it's starving for fuel or something. A short hesitation, then the power returns. It is especially bad going up hills, and when the engine is cold. I have changed the plugs (the old ones looked pretty good), oil change, fuel line/injector additive, new air filter. Nothing has worked. I thought maybe the fuel filter had some buildup, but found out that it is attached to the fuel pump!!?? I'm not very impressed with that from Jeep. I did look into the throttle body and under the "butterfly flap", there was some black buildup on the walls of the throttle body. Any advice?? It comes off, and is thick, like something you'd wipe off the side of the engine.
One possibility on my 123 error, I read somewhere that the airbag clockspring going bad can cause this check engine light error to occur. Any good advice on fixing?? I still don't think that will fix the running problems......this is getting real frustrating.
HELP!!!!
