    >>I just tried my friends identical 308 FI computer.
    It had voltage from the green O2 wire & FV reading on dwell meter changed.<

    What happens with his computer in your car? Chances of having a buddy with *just* the part you might need to diagnose this without having to actually buy one are somewhat slim... make sense?

    His car is just 2 months newer (exact same part), all the readings became normal with his cpu.
    I have a nos cpu sitting here now. I will install it this afternoon and report back.

    Well, the jury is back.
    It was the FI computer.
    Installed nos computer,
    everything as it should be.

    A big thanks to everybody that help me along the way,
    it would have been impossible for me to diagnose on my own.

    Thanks again guys.....Larry

    Larry, I wonder if someone (electronics expert) could find the fault in your old computer and get it working again...either a bad solder joint or bad component I would suppose.

    I looked real close, could see no visibly bad components or cold solder joints (that is the failed fi computer in post 24)
    I also thought it rather strange that it failed while I was driving. Most electronic failures I have encountered occurred when restarting....

    Nice!

    Grab Tom and bring the thing to Washington Sq. on Sunday morning. 10:00

    We'll be down there with the green car and the GT4 if you can make it.
