runs great / failed emission test
Washington state. Hydrocarbons: at cruise, allowable limit 150 ppm, actual 285. Idle, allowable 220 ppm, actual 361. CO at cruise, allowable 1%, actual 7.5% and idle allowable 1.2%, actual 5.37%. OH NO not a catalytic! Those cost a lot of beans. I thought when a cat went bad, it got plugged up & car won't run. So maybe I didn't need to spend $75 on a dist. cap!
