I have a 1994 Honda Accord. 4 cyl with 138,000 miles. It runs very rough at idle. Once I give it gas and its going it runs very well and has normal power/ On th road you would never know it had a problem till you come to a stop and it starts shaking.

If it does this at idle it may be a worn engine mount. My 92 accord does it very roughly in reverse when cold and at idle in drive. Another tell is if your car also shifts a little rough.

Let me add an easy and typically free check. Take the EGR valve off and clean it.
