The timing belt tensioner recentlly broke. The timing belt jumped and messed up the timing. I replaced the tensioner, belt, and realigned the crank and cam shafts. It stated up fine but has been running rough. I check all the spark plugs and wires which are only a few months old. Checked the timing with a light and it was within normal specs.

Today I got a P0306 code. Cylinder #6 misfire. Any ideas if this is related...
