Default 1986 Ford F-150 during issue

I have a 1986 Ford F-150 with a 5.0 fuel injected motor. Today I was driveing itís about 42 degrees out and it was ode long funny and then when I go to stop it wonít to die and died on me once. I changed the iac valve 6 mounts ago CSUís wit was doing this same thing now Iím wondering what it could be? Can it be the EGR Valve or something I else? This just started in the cold today. If I put it in nutral and rev a little while stoping then it wonít die.

This is very difficult to follow....
But along with other components, your new IAC is suspect, remove and clean, check the tightness of the connector.

Check for Codes, run KOEO & KOER test, let your computer tell you what it knows;

Engines are easier to diagnose over the internet when all the codes are listed, and in order of test.
KOEO - (O) Self-Test Codes =
KOEO - (C)(CM) Continuous Memory Codes =
KOER - (R) Self-Test Codes =

Make sure your A/C, Heat, Radio, etc. are turned off when testing.
Do you have any Non-Stock modifications?
(Air Intake? Smog System? Exhaust System? Ignition System?)
