my 01 SLS has had a rough idle for about 3 weeks. it bounces from 600-900rpm's. drives fine down road and never stalls. these are the only codes that come up. i describe it a bit better in my last post... thanks for any help

 

ok so i unplug the IAC and the idle is perfect. I have been tryin everything. I might have found a vacuum leak where the intake manifold meets the throttle body... i sprayed a bit of starter fluid towards the bottom and engine reved up a little bit. is it ok to drive the car with the IAC unpluged?? It runs like a dream with it unpluged.. not saying forever but until i have time to take the intake manifold off and get to the bottom of this vaccuum leak??
