Engine performance suffers after fully warmed up?

Hi -

I have a 92 Honda Accord EX with approx. 140,000 miles. Motor sputters - most noticeably at idle, then gets less noticeable as RPM's climb. Obviously this negatively affects performance in general but curiously, as the car warms up, performance gets worse. Once the motor hits normal operating temperature, car starts bogging down badly at low RPM's. Only when revs pass 3000 RPM's does the motor seem to "wake up", but even then there is still a noticeable lack of power. Changed the spark plugs/wires but there was no noticeable improvement. Paid $100 for fuel system cleaning at auto shop and there was a small improvement, however, all the symptoms are still present just not quite as severe. Any advice is much appreciated!

How about the distributor cap and rotor. Another thing I would look at is the timing. After that without a warning or CEL I wonder about the converter. What do you think losone?

Check engine light on the dash. The little picture of an engine that lights up when you turn on the ignition. If it stays on then you have some additional information from the computer to assist with the problem.
