So, I just picked up a project FJ55. It runs, drives, and needs a new interior and headliner. One look under the hood and I almost passed out. There seems to be a TON of smog crap and about 100 ft of vacuum hoses, most look hooked up, but the engine runs poorly. No smoke, no miss, but won't idle or accelerate well. My gut instinct is to tear every bit of that crap out and install fuel injection. Any reason I should suffer through getting all the factory crap to work?
