the CO% readings were high. what might be causing this. pcv, egr, vac leak? any help would be much appreciated. this is on a 1987 Grand wag, 360, auto tranny, w/ about 130k miles.

These were tips a old hot rodder guy once told me.. He said- Run Premium in the few weeks leading up to the test day.. Do a good tune up, adjust timeing, check plug wires, clean or replace sparkplugs, and get your motor really warmed up before going to the test.. the warmer it all is the better you'll test most of the time..

Did you go down there with the top off? I bet that was a site to be seen! Good thing we have been having this good weather!

High CO and / or high HC means you are running a little rich.
