High idle

I just went out this morning to reset my ignition timing - found out that it was set to 5? instead of the normal 10? - and after resetting it, it was idling at ~1600 -- way too high. It was a solid 1600, but even after warming up, it still rested ~1000, 300 off from the standard 700. ISC? MAF? IAT Sensor? Or something I'm totally missing... I cleaned my ISC about 2 months ago, tested my MAF 1 month ago as well as my IAT sensor. O2 sensor is ~3 months old.

I couldn't find anything in the TSRM that dealt with a high idle; only rough / erratic, but mine is smooth. Ideas?
