You may need to clean inside the throttle body. YouTube has videos on how to do it. Also, your Idle Air Control motor might have carbon build-up in the passage for idle air. Take the motor off, and clean it gently and check the air passage for blockage.

Sounds like you have a air bubble in the cooling system. What size engine? Did you open the bleeder valves when you refilled it with antifreeze?

Check your throttle body gasket, if it's leaking unmetered air it will idle high, this coupled with a bad ignition coil, plugs not properly gapped or old/worn as well as old/worn spark plug wires will cause a misfire that may not trip the CEL light. Also check your idle air control valve to ensure it's working and clean on the inside of the throttle body.

Sounds like it could be the Idle Air control valve. Also could be leaking air into the fuel injection somewhere.

My 1991 4cyl toyota pickup died while idleing. What are some suggestions on things to look at?

A diagnostic scan is always a good place to start, even if there is no check engine light on. Ignition...are you getting fire to the spark plugs? Fuel pressure, fuel pump, clogged fuel filter, air filter not restricted? Battery fully charged, terminals clean and tight? These are a few basics needed for proper engine mangement.
Good luck...hope this helps...please rate me a fixya.
