So far, I fixed a grounding issue with the O2 circuit

What did you fix on the O2 sensor? Was the problem limited just one of the sensors or both??? Sorry for all of the questions but mine is doing basically the same thing I'm getting tired of just putting in parts, at a great expense, and not fixing the problem.

jeff if i can ask what were the o2 sensors acting like that caused you to ck them.? i might have an intermittent issue with my 92.

okay.. there are 2 grounds OUT of the ECM, one right, one left. both tie together to one ground lug. somewhere from the tied point to ground the line was open. I tapped a new wire in and grounded it that fixed the O2 issue.

with no ground from the ECM for the O2 s I was reading .45v ALL the time on BOTH sensors
