part time idle trouble

ok, recently my fc has been idling rough, but its only once in awhile. most of the time it idles perfect but every now and then itll rev up and down while idling. there are no air leaks that i cant find, and ive removed all emmissions, plus removed all cold start and dash pots. im runnin 112psi on each rotor with a small street port. i cant figure out whats causin it?? any input would be greatly appreciated.

This. Removing the thermowax and BAC will cause idle problems when cold.

and/or

Your TPS is is faulty/misadjusted causing the idle to bounce.

see i thought about that, but it does it at any temp. its just a random thing that just happens once in awhile. and the tps is good, i check and make adjustments all the time as needed. im not new to these cars or problems but this time i just cant figure it out. ive checked everything i can think of.
