Idle Issue

[yellowbuzz]

I have a 94 4X4 22RE just rebuilt the motor but now I have a idle issue. When I start the truck cold it runs fine but after I stop say at a store for 10 to whatever as long as it does not cool all the way down, it idles down to 400 to 500 rpms ( fac spec 750) and will start to idle ok after I run the engine up a few times or start driving agian.
Any ideas ?

Could be your IAC . When i changed my motor in my 93 with a 22re it would idle way down the speed up then slow down again. Be sure to check your vaccum hoses on and along your intake. I dont know if you can buy just an IAC by the way you may, I just used the whole other throttle body off of my other engine. Let me know how all this info works out.
