98 Gs300 Vsc, Vsc Off, Check Engine Lights

Took it my local Autozone and they came up with 3 different codes. P0120, P0155, and P1349. It idles rough at normal operating temperature in park and drive.. Runs smooth up until then. Runs fine going down the road with very little hesitation. I replaced the oxygen sensor (bank 2 sensor 1). I don't know what to do besides going to the dealer. Anything else I can do for these codes?

Just picked up our 2001 GS300 from the shop today because it was throwing the same P1349 code and had the same symptoms. The shop found the Oil Control Valve (0CV) to be malfunctioning and replaced it. I don't know how to test it but know it VERY easy to replace yourself. Fixed our problem!
