Idle on 94 LHS

I got my LHS running again, it jumped timing.
Now the car wants to idle at 1800 rpm.
Is there an idle screw that I can back off or how do I slow the idle down on the 3.5 engine?

First look for a vacuum leak.

I looked for vacuum leaks and don't see any at all.
is there anything else that could cause it to idle high?

i would check the timing again
