Air Fuel tuning

Can anyone shed some light on what might be causing the air fuel at idle to be different after driving the car.Setting the air fuel to@14.7 sometimes the car will read really rich or sometimes lean.Then it will eventually go back to14.7.Any help is appreciated.

Can you be more specific? How long is staying rich or lean and how rich or lean is it (actual readings)?

We set the car to 14.7,it fluctuates between 14.2-15.1 just sitting there at idle.Drive the car for a little while and stop to see where it idles again,its usually fine.Turn the car off for a few minutes and when its restarted its lean, sometimes 16.1.Then it will gradually come down back to 14.7 area.Seems like15-20 secs to get back to the correct air fuel.Maybe were doing something?

This sounds like completely normal operation. You may want to add some more cranking fuel and post startup enrichment.
