" I also noticed that there was a little bit of rotational play in the crank pulley. I know that the keyway in my crank is a little fudged from when the original pulley came loose, so if the pulley bolt loosens a little, the crank can wobble. This MUST be the cause of the misfire."
you said it yourself. The wobble is not good. the tolerance needs to be proper all the way around. I would rotate the engine by hand and put a gapper that size for tolerance which is (I think) 1.4 mm is the most you can go so stick one that size (and it should attach itself to magnet) rotate engine and see by eye if the gap is lower or higher.
Whats the part number and do you have picture of how your vr sensor looks like.
Cause Iam looking online everything that shows up for a taurus crank sensor shows this we could have different ones. I also searched my part number and for other v6 fords that have EDIS> first time the net doesnt show the right parts......
Heres what shows up for a taurus 1997 crank sensor
Is yours a one bolt sensor where it mounts? Mine is 2 and its angled part # on it is F0EE-6C315-A2B Could be off an explorer I guess. Heres a pic
Edit I found it. It seems like its for 4 cylinder Fords I dont think that makes a difference. Except everywhere I found it there no price I guess and everything tomorrow is closed!
