I have which pins on sheet, just want to make sure I get the right ones when I head to the shop tomorrow. I'm not sure if they're numbered or what? found a place that would do it $10 bucks. One place told me $50!

I hope it works out for you.

makes 2 of us this resolves it end of June new tires and Michigan mile here I come

if not to zzp I go, but the whole random misfire leads me to believe this as did darth fiero. I'll post back

Clear 16 & 18

I do the crank relearn via the HP software/laptop route. I don't believe that you can do it by jumping pins at the OBDII connector.

C-16 & C-18 need to be grounded to make PCM think the auto trans is in Park. Also need 12v from brake switch to be present, and the then brake depressed removing the 12v on B-30(?).
You can not cause CASE learn by jumpering, it must be commanded externally, but the above conditions must be satisfied to fool the PCM that there is an auto trans present.
