Take the throttle body off and clean it really good, make sure the idle ports are clean and check the outside of the throttle body and make sure there are no holes rubbed through it. I had a truck in doing a similar thing. I found a hole rubbed through the casting on the bottom side by the butterfly shaft. Changed the throttle body and problem solved. I'd also check sparkplugs.
