    have you checked to see if your coil packs are giving enough spark?

    Did an inline spark test and they seem to be giving good, adequate spark.

    will the GM texh 2 tester reveal a dam knock sensor?

    or how to test a suspected bad knock sensor?

    thanks

    Having the same problem I think it is my o2 sensors because i installed my headers and spliced my sensors to make them long enough...And I drove in a lake(big puddle) and ever since I've been misfiring and getting jumps on the low RPMS. Ill try the corvette Rear o2's see if thats it if not iM going to take the motor out and shoot it!

    I do notice if I go through deep water that my car bogs, but I think it's sucking water in intake through the filter.....

    Mine also jumps rpms when it's running low rpms and is missing bad.

    But I've noticed with 40-60psi of oil pressure it runs fine and no popping through my exhaust at all, I suspect my oil pump. I need to replace it anyways because once it gets to temp it drops to 20psi.

    I never heard or seen a case where splicing your own o2 sensors didnt have a negative outcome at some point.

    I did the same splicing my own wires (ask Y2KPewterSS about it...it sucked) they lasted maybe a few months. Once the rains started, it was only a matter of time. I was surprised they lasted so long actually.
