    Is there a known problem with the harness or the computer of '93 240?

    I had the AMM and the coolant temp sensor replaced, but still get code
    1-2-1 and 1-2-3 occasionally. Unplugging the battery seems to solve
    the problem for a while.

    For 121 make sure that the coil wire is not touching
    the maf sensor harness
