    Re: FI code 26

    I haven't yet figured out how vacuum hoses or the five way T could possibly have anything to do with a FI code 25 or 26, maybe one of our digital tech gurus can explain it to everyones satisfaction. If the failure is totally unrelated to wiring or a failed sensor, seems to me that might point to a failed ECU throwing an erroneous code, but that wouldn't explain the 4k rpm threshold.

    FI code 26

    Iím of the opinion that while the codes do reflect particular FI issues, I donít believe they are exclusive. That is to say if the knock sensors, ECU and associated wiring have all been replaced and code 26 still comes up then thereís every reason to suspect that something else is amiss.

    How many hard high RPM miles (not just garage blips) without codes since the Tee clean up?

    About 200 miles round trip, blasting down the Pacific Coast Highway, and several little twisty mountain roads, along with a couple hours of freeway mixed in, why?

    Perhaps the clogged lines/tee were causing the ECU to throw an erroneous code?
    I'd love to hear what our digital tech gurus have to say as well.
