rough idle at cold start

What is your question?

123,000 miles. Engine idles rough at cold start unless I increase to 1500 rpm for 1-2 minutes, then fine. Replaced plugs, wires, filters, cleaned fuel system, yet problem persists. Any suggestions?

Any trouble codes stored? Try some fuel injector cleaner. Check for vacuum leaks.
