I verified base timing with a light. Still at 10 degrees(not like I thought it would have changed)

EDIT Also confirmed dwell maintaining at 2.1 at idle using the realtime display and dwell adjustment. I am still getting misfire at idle.

EDIT EDIT New plugs and wires gaped at .033

EDIT EDIT EDIT Compression 190-195 all the way

An Update. I went through the cop harness and checked the circuitry with a multimeter. All cleared ok( I think). I was basically looking for consistencies across the coils test trigger tach + and grd. Then it hit me which probably I should have checked earlier but anyway I thought to my self what if the fpr or map isn't getting the right amount of vaccum. I figured I give it a shot and I replaced the hoses and T. We'll so far so GOOD. Car isn't missing just idle fluctuations which I'll clear up when I go tune tomorrow. I have been running in pwm warmup to filter out the possiblity of a bad PID tune. Anyways I'll touch base tomorrow or Monday with results.
