It does not happen all the time but most of the time when stopping the whole truck just starts shaking really bad. Thought it may have been a plug or wire problem so we replaced all of them, but did not help. Not sure if it could be IAC valve or what?

Scan for codes first then try cleaning throttle plate on both sides with choke cleaner and IAC hole then get back to us if any codes. Also, check for a vacuum leak like a hose off /broken/etc.
