car starts to vibrate when moving or stopped with engine running. intermittent

you may be right 2 out of 2 answers the same thanks

thought you were right but It turned out to be a clump of dried mud on my fan motor. that's why it was intermittent. fan runs when called for

That's a new one! How did you get mud that far up, and that much, the engine?

? New indeed!!! ?
