I bought an fj60 that had been sitting a long time and the first time I went to emissions I failed misserably. Not knowing much about cruisers and carbs and vaccum hoses at the time I immediatly took it to a shop that was supposed to know them inside and out been working on them for years etc... Needless to say he gave it a "tune up" told me I should spend 3k rebuilding and for the mean time I should rejet it and it would run like crap pass and then have him rejet again all to the tune of 400$. I kindly declined paid for the 140 tune up / spark plug change and supposid diagnosis and was on my way. First off I didn't belive him that my 60 wouldn't pass, 150 k miles didn't burn oil doesent smoke and the po even put a new cat on last time he took it to emissions he told me with a tune up plugs wires etc. Secondly it seemed rather dishonest to jet it pass rejet and a 400$ hassle that didnt fix the problem. What really rubbed me wrong is when I started reading and learning about the crazy vaccum lines I noticed some were off/ ripped/ pinched. I really had a hard time seeing how a supposid cruiser expert missed all of this so I looked at the diagrams put the lines where they were supposed to go replaced most of them along the way cleaned my carb changed the air filter ran some seafoam through for a week and a half took it to the emissions shop and passed with flying colors. I live in Arizona and have to pass some pretty strict emissions so it should be possible. I would think something with the emissions systems isn't hooked up right or is not functioning. Make sure you warm it up really well before the test though I drove it on the highway for about 30 minutes before and don't shut it down until your done.
