@itsa300zx I will try to clean them or pickup a better sub harness. My local junk yard has 3 Z's in there. I will go there tomorrow. @GRIMM so you have had Z's in the past with all my symptoms(spark, fuel, air) and have dead cylinders? And your issue was the sub harness? That makes me hopeful and tomorrow I will let you all know. Truly appreciate all the help.
