Question about 1991 Chevrolet S-10 Blazer
Clean your Throttle body with throttle body cleaner or Deep Creep made by Seafoam. When the carbon and varnish build up in your throttle body get's hot, it gums up the IAC (Idle air control) valve which help moderate your engine's rpm to keep it from stalling.
If the IAC is stuck due to the gum of the carbon and varnish in your throttle body, you have stalling issues which you have described. Start with that and replace your air cleaner filter since your going to clean your throttle body.
