I HAVE A PROBLEM WHEN FIRST STARTING OUT ON A COLD MORNING. THE ENGINE BUCKS AND MISSES WHEN ACCELERATING. ALSO IT IDLES VERY ROUGH WHEN SITTING AT STOP LIGHT. IT ACTS THIS WAY WHEN THE ENGINE IS WARMED UP, BUT NOT AS BAD. THE CEL IS NOT ON, SO THERE ARE NO CODES STORED. I REPLACED THE FUEL FILTER AND INSTALLED FUEL ADDITIVE TO THE SYSTEM. HAD THE THROTTLE-BODY CLEANED AND STILL HAVE THE PROBLEM. THANKS FOR YOUR HELP!

I think I would try a cleaning of the iac motor and egr valve. The carbon build up can cause these symptoms, and sometimes with out codes set.
