up and down idle

[95tsiawd0330]

I know there is a lot of threads out here about idle problems and i have read every thread there is am just hoping someone can suggest something else that i can try to do that am over looking.What i have done already are....BLT,replaced throttle shaft seals,new throttle body gaskets,checked isc and it was reading 41omhns for all the coils,took apart fiav and screwed fiav all the way in until it stopped and removed coolant lines from fiav i know its not the best way but it does work and free ,replaced bisss screw with new o-ring,also checked timing (5deg) and timing belt and marks line up great.So iam out of options now.I have my target idle set at 800rpms and it will idle smooth for 30 secs then it will go to go anywhere from 750 to 850rpms.Can someone tell me something else that i can try to do.I want it to idle smooth so i dial my car at idle then i can start to get down on tuning

I think the IAC is supposed to be around 28-31. I could be wrong though. I would also try doing another boost leak test.

I done three BLT and there is a video on you tube that says if you have a ISC with higher impedance ISC motor that it will still work is this true?????????the name for the video is DSM ISC motor testing & Replacement by jafromobile it says that at 1min 30secs
