Maryland emissions are driving me crazy.I just failed a third test this
evening.

My previous test on 1 November gave these results:

                                      HC
CO                   NOx

standard                         2.40 GPM       80.00 GPM       3.00 GPM

mine                               0.9921 GPM    12.3648 GPM    4.2152 GPM

I subsequently replaced the oxygen sensor, catalytic convertor, spark plugs
and wires.

I got these results this evening:

                                       HC
CO                   NOx

standard                         2.40 GPM       80.00 GPM       3.00 GPM

mine                               0.4208 GPM   5.8560 GPM      3.1568 GPM

I am now at a loss to know how to proceed to get it to pass. I know what to
do to get a waiver but I'd like to know what goes on. What are the likely
causes? Incidentally, the cat conv I replaecd appeared to be in fine
condition.

What do we think? I would like to hear some wisdom.

Cheers,
