Need to bump this post... Ive done what 00 daytona said.. However i also have the throttle vibration also at idle... Did you fix it?

Ive changed, dog bone mounts, ttans mount, new lca's, ball joints, tie rod ends, subframe bushings (im at 271k).

I just ordered strut mounts and engine mount once i do those ill see... Hoping for the best cause om going nuts oh... Even changed harmonic balancer.
