ok i've had a little vibration in my car lately and i noticed it's gotten worse after racing last week. it happens between 1000-2000 rpm range when idling cold. it isn't noticable when warmed up idling or while driving. i'm suspecting a mount because i also just noticed a triple thump when the car is in 4th gear with the torque converter locked. it happens when i let off the gas while cruising. it's not to loud or anything but if your listening you'll hear it and feel it. i let off the gas and it goes thumpthumpthump in very quick succession. tranny mount? or engine? what's the best way to figure it out? thanks guys.
