    i forget the letters but i think it is the two on the ends.
    89 Coupe with parts stacked inside of it and about 30#'s of dust on it with no end in sight. :weird:





    Although I am collecting parts for a 12.5:1 393 :D

    frank, what scanner is that you have? i have one of those auto x-ray scanners & never used it, can these check MAF voltage?
    thanx for the input guys.....

    Its MATCO's "Determinator" pro.
    shows full live data, slow codes, fast codes, Runs actuator tests, clears codes, records, glitches, troubleshooter.....You know the typical $2500.oo scanner. :p

    wow, sweet frank, ill have to swing buy & check that out...........i have this auto x-ray scanner that checks all diagnostic codes, clears codes, etc as well as live data retrieval. i got it when i was panning my water injection so i could monitor the ACT temps before/during/after the water injection.......never got around to checking it out, i wonder if it checks voltage at the MAF??!!
