Why does my 1994 Toyota pickup stall when I stop? When I rotate the idle screw to the left it wil Idle fine, but when I rev the engine I can see the screw turn the opposite direction and the engine will eventually stall.

I checked the distributor cap rotor button and see no problems.
Hello and thank you for trusting Just Answer with your question. I'm Dj and I will work with you on this.
Are you talking about the stop screw that is for the throttle plate or the air bypass screw?
The throttle stop screw should have a lock nut on it. If the air bypass screw is turning, I would just use a drop of Loctite on it to keep it from turning after it's set.
I'm not sure if this answered your question. If not, give me more information about your problem so I can better help you.
