Emissions failure

[sharpshooter33 at adelphia.net (David Brown)]

I used to pull the plug on my O2 sensor and it would run lean for the test 
and pass.  If I ran it thru with the O2 hooked up I got rejected every time.

Glad we don't have to do that political B.S. anymore in Ohio.

Somebody got rich on those check stations.
