93 accord has rough idle but runs just fine throughout the rpm range
the check engine light comes on after it warms up and it has 246,000 miles.

Re: rough idle

Check for vacuum leak. Also inspect your plugs, cap, rotors, and plug wires.

Check your codes first. The ECM is trying to tell you something. I've had this happen when a customer's Top Dead Center sensor decided to take a sabatical.
