Some back info, I bought this car last Oct with a current E041. I replaced cam sensor with a borg warner, ran fine for 3 days, the e041 came back-ran bad, replaced cam sensor again, in about a week the e041 came back-ran bad. Replaced entire dist. with a new one, ran perfect for 1.5 months, then it sat in garage for 2 weeks, went to start it up and bam, running a little rough and a current E041 again. It mostly runs ok this time with a current E041, when the light is not on however, it runs awful, when driving the light will go on and off, but 95% of the time the ck engine light is on. I replaced ECM with a reman one and no difference. Thinking of trying an AC Delco hall effect switch, any other ideas? no other codes either.
