It's a ca thing. There is a ca emmisions truck. I have one. It has two cats and four o2 sensors. It sucks when you are trying to figure out which one is bad. It;s good for adual
I was under there earlier, but to be honest I'm accustom to a 1975 straight 6 block, so O2 sensors are alien territory to me right now.
