I recently acquired a wierd vibration at idle and up to about 2000 rpm...the vibration is very light ..and in drive you can feel it almost as if the exhaust was vibration only at 1500-2000 ...in the beginning of all this I thought I was only drive line related so I installed. New trans mount...didn't help the I re adjusted my exhaust...that didn't help either...then I figured out it was a little off at idle so I begin to double check all of wire and plug...figured some looked OK and some looked leansaid **** it I'll replace them all.nothing.no codes..the 02s work fine...runs great under WOT....I don't know where to go from here..hers a video of my crank pulley it's slp under drive I installed it to spec over a year ago do they go bad!?
