left work today everything is running fine, untill i get the first and every one after- stop sign or light, it would die it would not idle some time it would but when i touched the gas it would die drive any speed it is fine just when starting or stopping it dies i have to shift to nutral to keep it running, i have a 2000 qaud cab with 5.9 engine the only mods are true dual exhaust trottle body spacer kn air filter system and a three inch lift. the only thing that i can think of would be fuel pump or filter but i belive the filter is incorpatered with the fuel pump, i can get a pump for $185.00, but i hate to be wrong and out the money. any body have the same issues or ideas. thanks

 

My truck did this and i found it to be the AIS or automatic idle speed motor. Mine is located at the rear of the air intake body on my 5.2L. It is an easy replacement with a wire and two Torx screws that hold it in. If you don't have a manual i would suggest you get one as it will tell you how exactly how to replace it. The Haines manual is cheep and has good info for most repairs. The part isn't very expensive. Good luck.

 

the problem was the idle air control valve $48.00 and two screws- done.
