    My dad said the he thinks its the flex plate, it cracks from the inside out youll have to pull the transmission and converter to do it.. 2-3 hrs to do but it will tell you for sure.. Since it didnt change with plugs out he knows for sure its mechanical on the outside. What happens is the crankshaft starts dancing inside when its got some miles on it and the converter wont move so the flex plate does exactly that, flexs. Id say its probably that..

    I'm thinking along the lines of what Andrew said.

    I bought a stethoscope today and I'm pretty sure it's the flexplate now also..

    I'm going to outsource the repair though, and have to sit out RC this weekend.

    Took it to a guy who does repairs out of his house, seems legit, he's pretty sure it's the flexplate too, and quoted me $425 (including the $100 part) which doesn't seem to bad to me.. so hopefully I'll be dropping it off tomorrow so he can get it knocked out over the next few days.

    That's not a bad price considering the transmission needs to come out.
