    Change the pcv valve. ensure you get the o-ring back on the new one.

    yeah i kind of have the same problem with the vibrating when a stop light and upon acceleration. I still havent fixed the problem but i just ordered shorter dog bones and going to replace lower motor mount and trans. mount and see what that leads to.
