HELP!...idle & trans. trouble

[RJRavalli@xxxx]

Just bought my DeLorean, and I've noticed that the idle is set
really high. Just took it in to try and get it smogged, and the
guy tells me that it is idleing too high to do the smog. I've also
noticed that the automatic trans is now having more problems
shifting than I've ever noticed before. 

Basically, why would the idle be set so high on this car? Is this
and the trans. two seperate problems? Hit me with your best shot...
what is going on here and how much is it going to cost to fix
this stuff?

This is really bummin me out here, guys (and ladies)...I've wanted
one for a long time and now it seems this thing is going to need
more work than I thought, and I (unlike alot of DeLorean owners)
am not rolling in dough. What can I do to fix this guy up and get
him into decent running condition again?

Please help...and thanks for all the good advice so far,

Richard
