Found this post High Idle When Engine Warm mentions checking the decel valve. Now to find that and check, turning down the idle worked but will it start when cold?
And look at this one High Idle CIS issue has more info regarding the decel valve.

Finally got the car running correctly 2/16/2009
Finally solved the stumbling problem. Turned out I had a couple of wires crossed. The purple and green wires that come from the MSD that connect to the "green" wire to the distributor were switched. At the moment don't even know how there are set now :) but I switched the way there were and presto it ran great.
But now, 2/20/2009 I suddenly get a high idle about 2000rpm once the car starts up.

Oxygen sensor related
Some posts related to oxygen sensor, testing etc.
CIS basic mixture adjustment info on voltage and mixture, not sure how accurate this is.
Mixture adjustment confirmation checking the mixture by testing the oxygen sensor at the test port.
911SC Oxygen Sensor more on testing.
and another O2 Sensor functioning
An explanation of the working of the O2 sensor, frequency valve etc CIS Experts, Advice Needed a nice detailed explanation.
More details Oxygen Sensor Voltage on what the voltages might mean.

"right to richen (CW). always turn it from lean to rich for final adjustment. if you do not have a way to check CO, here is how i set mine. turn it CW until it surges at idle then back off a tad. blip the throttle and if the RPM's dip down then come back up to idle, it is too rich. turn it CCW about half a turn then back CW a little less than how far you turned it CCW. blip the throttle again. repeat until it no longer dips down when the RPM's come back down. mine is set so it has just a hint of wanting to dip down when i let off the gas. drive it and check again. i later had mine checked and it was dead on 3%." by T77911S
