Service Engine Light issue

1997 Z71 350 engine. My Service Engine Light comes on after starting and sitting at an idle for about 30 seconds. It will also come on when the engine is warm during idle (again it will take about 30 seconds of idle). As soon as I put it in gear and go the light will then go out in all cases. The truck seems to run fine, no noticeable degradation in gas mileage or acceleration. This all started after I had an oil change done on the truck. It is not the gas cap as I have checked that. The air filter has been replaced. Any ideas?

Make sure they plugged in the AIT sensor back in the air ducting.
