AND.. not all smog machines are equal.

I just did mine last week. Had to go to a Test Only center, so I ran it up on my machine, and it was beautiful.

Then, I leave it running, drive 3 blocks to the other place, which has the same brand machine as mine, and shit if i didn't just barely pass.

I found out later that his machine needed servicing.

I passed...because mine was super clean to begin with....but I guess those poor suckers with dirtier exhausts are all failed that day.

There is a wide margin of 'legal' machine calibration. I had just had my machine serviced the day before, while the other guys machine really needed it.
