idle flunctuating!

[erc's_gsx]

i just recently installed a used ISC motor coming off of a 92 tsi awd a/t. once i started my car, it idled fine until two seconds later it slowly started to climb to 1500 rpm and flunctuating to 2000 rpm over and over. i tried adjusting my BISS screw but that didnt do me any good. my last ISC motor didnt do this, but it did flunctuate from 250-500 rpm for a second then would idle at 800 rpm and this would happen each morning i'd start up my car. I tested my old ISC and one of the coils were bad. the person that put on the ISC i purchased was too lazy to test the coils. so i guess tomorrow morning im gonna have to check out the one i just put in. maybe i got ripped off for $25 off dsmtrader, what a punk. i purchased a 1g bov and this crappy ISC motor from him for $50. maybe when i put on the bov it would also act up on me. oh well. any inputs on the idle flunctuating?

ok, I just had "some" (read alot) of experience with idle speed motors.
they still can be bad even if the coils are ok.
read this and all of it!

also are you sure that 1G ISC motors fit 2G-s?
