When its cold out or all winter the truck runs fine but in the summer the engine runs rough
it will start fine but when you need to accelerator its sputters.

Has the check engine light come on? Have you checked for vacuum leaks? Also, you may want to have the temp sensor tested. If may be running too rich for summer time.
