got my 84 fj60 smog checked yesterday. hydrocarbons are at about 2500, need to be under 220. this is the first time it's failed the check, i've owned it fhe past 6 years, 4th time i've tested it (first time when i bought it, the every 2 years after).
testing lead up - about 1/2 tank of gas, 5 minutes to highway, 5 minutes on highway, then ~10 minutes in stop and go traffic to the smog place.
any thoughts on what i need to check first? from browsing, seems the air injection system needs to checked to ensure it's working. would that cause such a high HC output?
i have about 5 weeks to get it to pass, otherwise i have no valid tag.
