O2 Sensor Question

[Joe Fast]

I have a friend who has a SOHC throwing check engine codes regarding O2 sensors detecting rich mix. I have been told that it could be the sensors them selves. He is also getting unsteady idle with the AC on. Any ideas? Anyone have these problems? Anyone have a good source for new sensors?

Do a search, there is a ton of good info on 02 sensors. Don't automatically assume the sensor is bad because you do not like the message.

Figured out the problem..... It was not the O2 sensors but the MAFS. Now that I have had the car for a while....and it began to run rough with the A/C on...I decided to look at the air filter. I had never checked it out because of the low miles on the car...Mistake. Not only was the filter clogged but there was a bird or mice nest in the air box. Box was full of twigs and paper. Cleaned it out and shook out the filter.. Presto no more Check Engine or rough Idle.
