Choke Trouble

[apstguy]

I'm having some problems with my choke. Here is what happened:

I went to Ceres (20 min. away from here) to go to my job (second one). I couldn't figure it out but my truck felt "funny". Something wasn't right. When I got into town off the freeway, my choke was on! It was at temp when I left! It sucked up alot of gas too. When I got there I shut of the engine and it started dieseling. WTF??? So I hit the starter again and killed it in drive. Stopped fine now. Took off the aircleaner to see if the idle stop solenoid was malfunctioning and it is fine. If I pull out the choke fuse, the choke turns off and the truck runs fine.

So what do you guys think? I could give it some gas and rev it a couple times and it would take the choke off, but next time I touched it, it would turn back on. How are the chokes hooked up on these electronic carbs? Could it be a temp sensor somewhere? Oil pressure switch? I'm stumped. This needs to be fixed soon too. HELP!
