I'm working on getting my stock, one owner (I'm the second) 1973 FJ40 back on the road after its 20+ year hibernation and I have a question about the emissions system. I know a 73 is a "transition" year so its a little odd, but what is the recommendation for the emissions equipment? I'm not in an area that requires any sort of emission testing so what is the best thing to do about the VSV? If its not going to harm anything or hurt performance I would like to just cap off all the ports and leave it mounted to the fender, however I've seen some threads where people say their FJ40 ran so much better when they fixed their VSV/emissions equipment so I'm wondering if I should go that route? As far as I can tell I still have everything that was originally installed on the vehicle from the factory including the belt-driven vacuum (?) pump so I can go through the process of revitalizing the emissions system, but if its not going to improve the drivability of the vehicle I'd rather not mess with it. I've confirmed that I have the original vacuum retard distributor (upgrading in the near future) that I know I want to have capped off from the vacuum system regardless.
I'm not going for a 100 point restoration....I just want a reliable rig to drive around on nice days. I'll definitely hang on to all the parts I have, but if I can just cap off all the ports and call it a day that would be awesome. If the consensus is to fix the emissions system does anyone have into on the 1973 specific setup?
Thanks and happy early Thanksgiving.
