I'm just not sure, but I think it may be in the cold start or throttle sensor. Any one have an answer?

It seems OK after the car is run for 15 to 30 seconds if I step on the gas and bring the RPMs up to about 12 to 15 hundred and then take my foot off the throttle and let it idle. The service engine light came on for about a week, then went away all by itself. But I still have this rough idle at start up some times. Thanks Chuck F
