Well the biannual air nazi test strikes again! 1987 Volvo 244, failed the "Fuel Evaporative Controls Function" and the NO (PPM) for 15 mph, but it passed fine on the 25 mph test.
The guy at the shop said I need a new cat and he wasn't sure what was wrong with the fuel evap. I did some searching and I checked the vent lines going to the charcoal canister and they visually look alright. I checked the gas cap and the seal looks in decent shape as well. Any ideas?
