I'm leaning toward the 1 tooth off theory. I had a 93 626 that that happened to while replaceing the timing belt. The same shop made that mistake but they corrected it for free. The Maxima does run good except when you nail it though.
I am considering going to the original shop, but given the history am undecided.
