And I Have searched!! Vibration in "D" and "R" only at around 1100rpms. Replaced the belt tensioner twice with ebay ones.. Then thought it was alternator, but after replacing with a new one no change!!
Does not vibrate with belt off!!
Should I buy an OE replacement tensioner and try that again, all other pulleys seem okay!!
Also replaced rear motor mount!!
Thanks a ton for any help!!
