As far as I know there are two chokes on my truck. There is an electrical choke, and some vacuum choke. Since I don't really know how to screw with these, I just let the thing warm up propery. If I push the gas down ALL the way before I crank it, one of the chokes kicks in and the thing sounds like death for about a minute and a half, and then the rpms races. I give it another quick butterfly to the gas, and it drops out that choke, and the rpms drop back down and it sounds good and idles fine.

I've got some similar bahvior to this. I have to give the gas a few stomps before cranking. She starts right up, and idles high for a bit, then I tap the gas and she drops into a lower idle. That was until the recent issue. Now I stomp the gast at start up and she immediately drops into the low idle. Then she runs fine for about a half mile before I get a strong exhaust smell and the idle gets rough. After a bit more driving she will stall out at stops unless I put her in neutral and keep a little pressure on the gas. Makes parallel parking great fun!

On the same side of the carp is a fast idle cam and a screw adjustment to set the fast idle. When the choke is fully closed the cam should be at the highest position. Adjust the fast idle for about 1500 to 2000 RPM.
As the engine warms up the butterflys should gradually open. Make sure they are fully opened when operating temperature is reached.
Also make sure that the wire connecting to the cap has voltage. This is an electric choke and it will not operate properly without voltage.
There are several other linkage adjustments related to the choke. Hopefully the rebuild company set these up right.
