The car is a 91..I did replace the PCV valves,related hoses,and a new MAP sensor...The problems started shortly after.. Is it possible I disturbed one of the DIS harnesses?..Am I able to try to screw in the harness tighter without pulling the plenum? I did check that all 4 plugs on the main PCM are seated properly.I also removed the cover underneath the check the pins on the Heibeck memcal.. They looked fine.. No other harnesses were ever removed by me and the problem just started out of nowhere..
