94 3800 won't idle up

.mm..indeed...the threads on the stem are straight, not screw type as I thought. My mistake then. I was confused by the symbolic in the diagram and the shape of the actuator that matches that of a rotary step motor...

Nope. My threads were a screw type...like you thought. It's hard to tell in that pic, but I THINK it looks just like mine. I screwed mine in. Lefty loosey, righty tighty. However, it never bottomed out. I don't understand why. I think that I should have adjusted in to the specified length and then let the PCM do it's job. Instead, I was having to deal with the high idle. I don't really think that had anything to do with me blowing the engine though. It had low-ish miles, but always smoked just a bit, had pretty low oil pressure, and I always thought I heard a slight knock.

I bought my aunt a little truck. I guess this is going to scrap. Is there anything I should keep? Nevermind, I just remember a late last night call. A buddy with an engine and several GM 3.8L vehicles is willing to give me $200 and a late 70s Ford van to take to scrap.
