1988 chevy truck 350 idles too fast

I have a 1988 chevy truck with a 350 in it that idles way to fast. Had it in the shop and they checked timing, put in a new throttle body gasket, and checked all the vacum lines. They said to change computers out of my other truck to see if that would help and nothing changed. My other truck is a twin. Any help would be greatly appreciated. thanks gary

Getting any check engine lights? Have you pulled the battery cable
to clear computer. You should be getting some sort of code.
Get some wd40 and spray around throttle body and see if you hear
a idle change, if so you have a leak still.
