Ok so i was goin to work and theres a rail road track that i cross everyday....but this morning as i was going over it (a little faster than normal, was in a hurry) and it was a bit bouncyer and as soon as i got over the tracks my car goes crazy....like its sputtering and misfiring and all kinds of crazy...well when i got to work i look under my car and the wires that go to my rear o2s one of them pulled apart....so i limp the car home....jack it up and rewire everything....it idles a little better but now i have a wierd tick at the back of my engine seems like it on the passanger side of the engine....almost sounds like valve chatter.....im at a loss of words here....ive got both a tune that turns off my rear o2s and mil elims on there....i dont see how that could have messed anything up....so i erased my ecm and reinstalled a fresh tune reset the computer and its the same.....better but still choppy and chatter at the rear of my engine.....what do the rear o2 wires attatch to? could that have gotten snadded as well??

My guess is that your wiring is still hosed. Are you throwing any codes?

could be an exhaust leak....maybe you knocked the header loose a little when you hit the tracks.

Good idea, demon. I should have thought of that. Damn, I'm getting old....

i dont have any o2 sensors hooked up and my car runs fine... minus the check engine light but ill deal with that in a few months when emisions roll around.

Thats what I was thinking, an exaust leak up there usually sounds like "ticking:"

Any o2 sensors??? Or just the back ones.

If you arn't running the front o2s, your gonna need a new shortblock sooner or later.

i just disabled my rear o2s cause they were melted and such, i hope emmisions doesnt pick up on that. i hope its just an exhaust leak or something harmless like that.
