Default Please help! 94 Firebird 3.4 OBD Code 82 runs with horrible misfire

Ive replaced the 3x crank sensor, tested new one at 1081ohms. I am also getting .2 volts ac when cranking. So i also replaced the ICM and still have the same problem.

Thanks to anyone who reads this and can help.

Do you have the manual? There should be the step by step trouble tree in it. Its not the kind of thing you can talk someone through. This type of diagnoses is normally done by grade A techs.

The only way I could help is to type what is already in the manual.

Yeah, i have the manual and went through all the suggested tests and everything checks out. Its driving me nuts. I even tested the coolant temp sensor, 24x crank senor and cam sensor thinking they may be causing the 3x crank sensor to act up and they all check out good too. I appreciate the reply if i figure out what it is I'll update this thread.

Thanks again,
Wayne

Im thinking i changed the plugs and wires about 2 yrs ago. I might go ahead and change them out in the next day or 2 it certainly cant hurt at this point.
