when the engine has not reached normal operateing temprature, the oxygen sensors are in open loop mode! meaning the o2 sensors are being bypassed because of to much emssions when the engine is cold. but let it completly warm up and if the ses lights turn on either tune them out or buy the simulaters! goodluck

You installed these and not a shop? If a shop did it I was thinking maybe they tuned them out?

yea i installed them, and ive drove it around for 2 days now its been warmed up and everything. but ive also noticed when you start up your car all the lights come on air bag, check gauges, seatbelt, etc., but still no ses light, do yall think the previous owner took out the bulb or something?

+1, If the light doesn't come one when you first turn the key to "ignition" then the bulb was removed....just have someone scan it to see what kinda codes its throwing, just to be on the safe side...personally I had my rear O2's deleted.
