After the three minutes or are you saying the rpm went back up after three minutes with the vacuum line off and plugged?

You will need a 1/4" drive socket set extension with a T40 taped on it from a kitchen tool kit to get the center bolt out. Then you can use a 3/8" ratchet and adapter to turn it.
OR you can buy one of these from snap-on:

ok i will try that and good info on that part i just had to stop because the head on my socket was to big to fit.but what would plugin those vac line do? i would have to reassemble a couple things first . to get it back startable not long after my last post i went at it...also when i bought the truck the upper manifold was loose so it woulndnt be a bad ideal to go ahead and replace that gasket. and maybe pop some valve gaskets on there to. weather is good today in st.louis so ill be under the hood for some time today and thanks.

Ok upper manifold is off found out the egr pipe was shot (i guess i found my exhaust leak) and the pcv was shot as well. i guessing with that pipe and pcv both broke and possibly letting air in maybe my problem would go away also egr gasket was beat to *****.. please let me know what you think.

It should run with all the vacuum lines off and there sources plugged except maybe the PCV valve.

ive replaced the iac a few times but before i did i noticed that the iac opens. i honestly thought to much because when it open the idle goes up a bit more.....but im back with the egr line and pcv the autopart store did not sell the pipe so had to go to the salvage yard and take one .... going to rebuild engine now hopefully this will fix it.
