Sputtering & Jumping problem no one can figure out

What is your question?

Honda has 240,000 miles with regular service done started sputtering and jumping while driving at various speeds. Distributer changed to include coils, egr valve cleaned, all wires checked for shorts, fuel pump checked out fine, ecu computer pulled and 2 others used to see if that was the problem, it wasnt. Spark plugs changed twice. Passed a compression test with flying colors. Engine light never came on and problem started randomly, and continually got worse. On our 6th mechanic (who is a wonderful retired Honda mechanic) and no one can find the problem. Car starts fine, no other electrical problems that have been noted. Any ideas?
