Just brought my 84 1.9 in for California Emmisions. I had them do a precheck
as I don't wish to get tied up in the California Gross Polluter business...

Results:
2500 RPM:
HC PPM 96  allowed 180    Pass
CO%  0.83   allowed 1.20  Pass

Idle:
HC PPM 502 allowed 150    FAIL
CO%   1.20 allowed 1.20   PASS

IDLE RPM 955

Seeing as the bus runs fine, hets 20 miles to the gallon, all I did before
bring it in was change the oil and turn the big screw on the throttle body
to even out the idle.

Any ideas before I spend big bucks to make this thing pass? My mechanic who
use to nurse these things through inspection doesn't do it anymore. His
friend down at the inspection station quit.

How do I pull the hydrocarbon count down without messing up the tenuous CO
%?

BTW - It would have been in gross polluter land.
