Hey all, truck starts and runs fine when its cold, a little rich till it heats up but runs ok. Once heats up, all is right w/ the world. Prob is that if i shut it down once it gets warm, for any period between 5 mins and an hr. It will refire ok, but then wants to choke down. You have to feather the throttle to keep it runnin, and it does that until its been runnin long enoguh that you have had time to run it up through the gears. I mean get goin fast enough the tranny shifted into all the gears, and then it will run fine. Any ideas? Thanks. Chris.
