again, to repeat some questions.....is it idle in park or in gear.....(assuming its an auto)......what does rpm changes do to it......are you sure it doesnt miss at all on take off.......is there any noise associated with it........and other than the vibration....how does the engine sound and feel.
all that asked, i have never seen it as a noticable vibration, but i have seen a reasonable number of tensioners fail. the kicker is i have never seen one that you could feel. if your ride is a manual, it could even be a clutch problem, and if its an auto.....it could be trans related.....ive even seen a fan clutch make a strange vibration. get back to me with all the answeres to the questions i asked....and also take the serp belt completely off....start her up, and let her run for 30-45 seconds or so (no more than 2 or 3 minutes MAX)......let me know if the vibration is still there. if it is, its not in the assesory drive belt pulleys. dont run it too long as your water pump and altenator will not be working durning that time and you dont want to cause any problems...........Marc
