I would check the throttle position sensor. It is located on the right side(pass. side) of the throttle body. Remove the air filter, and the rest of the filter housing. The sensor will have wires going to it, and can be removed easily. Once removed you may be able to clean the moving parts with var sol or something similar, lubricate with wd-40 or jig-a-loo or similar. Replace the sensor and give it a try. The possibility of it being that are not that certain, but if i were sure i would recommend replacing it. There is also a possibility that the temperature control sensor may be acting up and thinks its cold outside and delivering too much fuel to the system... Hope this helps
