Feeling confident, with the new O2 sensor in, everything was feeling good!
Took it back for a Pre-test....
It failed again on HC at the lower speed...
Oh, and just for good measure to give me a kick in the nuts, between the morning start and the smog station... the CEL bulb blew, adding a visual failure to the insult!
The reading were pretty similar... failed at lower engine speed...
I got under the car...
I had not done this before, but I banged the Cat... which is not the OEM unit...
It rattled...
So, I decided to replace it..
Here is CA, its not so simple or cheap...
But here it is... the correct magnaflow CARB approved cat..
Cut the old one off today...
The pictures will speak for themselves....
I am feeling like that could be the issue!
