HI
I was out of town for a while.
Just went through my smog test results going back to 2004 and made a spreadsheet of the results.
There were times in the past that the HC was high but just passes.
It seems like with the latest test all measurements are on the higher side , even the ones that passed. I am going to take some voltage measurements of my O2 sensor with a voltmeter to see how it is functioning.
let me know if you have any comments to my results over the years.
Thanks
