I am glad we all got to have fun with the font size

I checke the O2 got 15 ohm my book says it should be about 20ohm so I dont know I hate to spend the money if I dont need to

 

Honestly its not a real problem, if you let your car worm up it should be fine. The way our o2 sensors work, their are 4 wires that lead to it, 2 are for reading, and the other two are for heating, chances are that function is broken so its not getting a good reading while its cold.
