After installing my new SS header kit, my '88 ran great.  But after a month
or so, the performance diminished.  I can't seem to find an exhaust leak to
explain an 02 sensor problem, so I try an experiment; disconnect the 02
sensor.  Now, the van runs great, even when cold.  If I run like this
permanently, can I damage anything?  Can I get the emissions checked to tell
me if the fuel/air mix is OK?  If not, where do I make the adjustments?

Thanks
