3.0 wont stay on
please help guys, my truck will start up fine but has a spuratic idle, jumps up and down a bit, well after driving it for a bit and it's warm. when i come to a stop it shuts off, when i start it it jumps to 1 and1/2 rpm them dies....what do you guys think, spark plug? fuel filter?

Unfortunately if it is a vacuum leak, it could be among any of the 3.0Million vacuum hoses in the engine bay. However if it's dying that readily, it's probably one of the larger hoses. Check the brake booster hose, and anywhere along the main air inlet from the air filter box to the resonator to the throttle body. One of the three parts on my air inlet tubing was cracked and couldn't get it to idle properly.
Might try spraying a little brake clean around some of the lines and see if the idle changes. TAKE CAUTION when doing this. The brake clean is flammable. I would advise doing this when the engine has cooled down a bit, but not overnight cold.

throdle body cleaned with cleaner and hoses checked, drivers side 3 spark plugs changed, it still sounds like a old ford truck. it does feel a little better. i do hear a hissing noise now that i've had it running in the garage. i have not kept it runing long enough to get warm. it's got a smokey exaust, light black/gray smoke (the cat and muffler is new ) i changed the oil and the old oil looked good. there is no leak around the engine or tranny, tomarrow i will xchange the 3 passanger side spark plugs then if i'm still stumped and advise here does not work i'm takeing it to the shop. thanks so any info

hey guys, well i took a viedo and i'm just waiting for photo bucket to upload it. you will be able to hear the truck run off beat, engine is pretty load but all stock, no fan shroud so you can't really hear much. the intake is hissing, i poped off a vacuum hose to hear what that sounds like. so after that i can hear nothing but intake so i dont think i have a vacuum leak. viedo will be up in a few moments
