1997 Acura Legend mileage: 122,000. Problem: engine runs very rough for about 5 minutes after start-up and then all of a sudden it runs fine. Doesn't matter if I've driven 2 miles or 200, if I shut it off and restart it, it still runs terrible for the first 5 minutes. I've changed the fuel filter twice, and the plugs are good. I had a mechanic check it with a diagnostic unit, and he found no codes showing. Any ideas?
