421

    Just got offefed a 421 and it only has one lambda sensor hole, my car has one in cat and one in the manni, so can i just unplug one and not to worry? And will my warning light be on?
    Thanks

    Tuck & sleeve the 2nd lambda out of the way so it can read clean air,that way the eml won`t come on.
