How can i check the idle air control (iac) solenoid in my ?

My truck has been idling very rough this year, recently my "98 ranger has been stalling at most every stop light or sign. It is a manual 5 speed ~ 2.5L engine. I have been working on this on and off for the last 6 months. I changed all of the spark plugs & spark plug wires. What advice can you give me to remedy this? Thank you for taking the time to help.

The iac needs removed. Have a helper turn the key from off to on. There is a pintel valve that should move on the iac. Also, check for vacuum leaks.
