22RE-inconsistent idle
My '94 22RE is freshly rebuilt with less than 100 miles. I was failing emissions horribly and throwing a code 21. I replaced the oxygen sensor with a new Denso unit, and now it passes emissions beautifully, but has a very consistent idle.
The idle is usually about 700-750 RPM, but occasionally will sit at 1100 when coming to a light after cruising, and won't drop down without a tap on the throttle. What could be causing this varying idle speed?

Can also be dirt / contamination on the throttle shaft or throttle cable, improper dashpot operation, sticking pedal (under the dash)... any of which could cause the throttle to stick slightly open.
