running rough at idle

Postby xxjerryxx123 [OP] » Dec 22 2010, 11:59pm

about a week ago i had to change out the sensors on my 5.3l and when i went back with every thing. i cranked the truck and it runs decent when its cold but when it warms up it runs rough i change the plugs and wires but it did no help and have not found any fuel leaks its a remanufactured engine and doesnt have many miles it has plenty of power while driving just a bad idle
