excessively high idle?

After I adjusted my valves and timing, I got my 89 350 running again, but the idle is really high in Park and Neutral, about 3000rpm. When I put it in gear, it slows to normal. The idle has been like this since I purchased the truck a 6 months ago.
Since this engine is computer controled, the idle is not adjustable. How can I lower my idle?

Thanks in advance,

Tim Moore
