				 Hall sensor... 
 I troubleshot my "miss" for months after I got my new setup. I had a $225 Mallory distributor that was nearly new, so I swapped TFI's. After going through everything again(i.e. wires, plugs, coil, grounds, etc, etc), I discovered the hall sensor crapped out inside the distributor.
 So much for that sweet billet distributor. $225 piece of crap. I will never buy another Mallory product again.
