I have a 83 F250 that just barley failed the max CO%
This engine is a 351 cu. and only has a little over 5k on it. The last time I tested it passed easily on the dyno. This time they gave it an idle test because they claimed it was too big for the dyno (37" tall tires x 14" wide)
My test results for the idle test were:
HC (220 PPM) my reading = 169 PPM
CO (1.2%) my reading = 3.3%
Is there anything "easy" I can do to lower the CO%??
I hardly ever drive this truck...could that be part of the reason it failed?
