That really was just a side note that probably dosn't apply to this situation, but I thought I would throw it out the in case it might help someone. Now, since you asked... Every once in a while, as I drove, the CEL would begin to blink. The trouble code was for a stuck TCC sol (Torque Converter Clutch). I did the reading, did the suggested fixes, and would still get the blinking light with the same trouble code. It hasn't happened since the replcement of the crank sensor, so I can't help but think that the two were related in someway. Possibly the ECU uses the crank sensor when determining torque converter clutch control, I really don't know.
