There are a zillion posts about idling engines, but I can't find this one. My '94 Cav, 2.2, shakes at idle, shakes fairly hard. It does NOT start hard, run rough off idle, use too much gas, blow smoke, hesitate, overheat or anything else. My only clue is that the temp gauge says 160 degrees. It rarely gets to 190. T'stat is new, tested in hot water with lab thermometer. Engine has been flushed, new plugs. 134K miles. NO CODES stored in computer.

It sounds like you don't have a problem with the way it runs so what about a problem with the mounts? Maybe you have a motor mount that is getting weak and has some slop in it that lets it jump around when idlind but when you give it gas it would take up slack in it keeping it to the end of slack and holding it steady there. Just a different angle to look at it. Worth checking out :?:
