My car started idling low immediatly on cold starts too, found out that my car was running on limp mode. The ENG SENS fuse had blown because of the O2 simulator was grounded out. Does your Reverse lock out work? I am sure other things could cause it to have the low idle too, but check this too.

Reverse Lockout is a solenoid on your transmission(6 speed cars) that prevents you from going into reverse when the car is moving forward. If the fuse blows, it will take two hands to put your car in reverse. Your Mass Air flow sensor, O2 sensors, skip shift, and reverse lock out are all on the same fuse,( ENG SENS). So the car also goes into a limp mode and runs like ***, and shifting into reverse is a pain. I am sure you would have a code though if this was the case.
