Your rough idle is most likely associated with the extra air coming in through the LIM it's not expecting ... get this fuel/timing maps massaged for the lack of the LIM secondaries and all will be good!



Any other possibilities? I'm having the EXACT same issues. Just replaced the LIM & UIM gaskets, my IAC looks new inside, and everything else seems to be good. But I get:

low idle(~600rpms)
rough idle(jumps from 500-700 a little faster than the tic-toc of a clock.)
dies on deceleration when pushing in the clutch, but only once in a while.
