Went thru AZ Emissions today 400E FCR

Recommended Posts

I deceided to lean the 400E more than last year to see what the HC would read.

Very lean stumbling at 1700 rpm had to bump the throttle once to keep rpms the there, engine temp 205, fresh oil, no oil in the air filter.


HC 168... idle std allows 1800

CO 0.37... idle std allows 5.50

PASSED it seems you can lean these way down without the HC going up.:smashpc:
