Exclamation 1993 ranger 4.0 4x4

i have a 1993 ranger with a 4.0. I am having a problem with the idle. it will run fine then out of the blue run very rough, buring raw fuel out of the exhaust. at times the RPM will race up and down then it will just run like it is loading up and the whole truck shakes. there is no engine light on when it does this. any help would be appreciated. PS change the plugs, still does it, also cleaned out the IAC valve, still doin it.

i Had this same problem with my 93. i would start it and it would idle fine for a little bit the the rpms would just go from 200-600 rpm. i found out that i had a vacuum hose disconnected.

correct right next the the brake master cylinder is a 'thing' with 3 or 4 hoses attached to it and 2 or 3 'stoppers' on it just check to see if all those lines dont have holes and they all have a good seal. i know that sounds like a small thing to make the whole motor malfunction but it sure does.
