  • That time again, emission question

    Past few years was close on HC. Any ideas to get it lower before i go up for a test. Last year put new plugs wires etc. 90 5.0 only mod done is BBK high flow cats x pipe.
    Seems to be in good running order no smoke uses no oil. Thought maybe a leaking injector so I put a set in last year didnt make much of a change.
    Some one told me to set timing up closer to tdc and pull the spout? And put in a little e85? Not sure if I want to put any in a car this old and 85% ethonal I would think make it burn even slower, am I wrong? Tips any one?? Or??
