How do I adjust the idle on a 91s-10 4.3 v6. Just install a rebuilt long block and got everything on when I finally got it crankthe idle is way to high. There is a assemble that holds the accelorator and cruise control bale and 1 other cable. Is it possible that was bent? Any can some tellme or show me a pic where the adjustment screw is? The fat chilton does not show me.
Thanks

I adjusted the idel on a full sized 4.3L recently. Sorry no pic's, but here's what I did.
In front of the throttle there was a steel cap in the throttle body (looks like a tiny frost plug on the front drives side on that motor)
I popped that out with a small screw driver, and there was an adjustment screw behind it. I just backed it out and it did the trick.
It's probaby only a 10 min job, and the hardest part was removing the air filter to access it.

Make sure there aren't any vacuum leaks, the IAC isn't stuck and the TPS isn't out of adjustment.
