lambda sensors

  1. #1
    Alright folks.
    Provably been asked before, so my apologies.

    Ive just received a 4 into 1 exhaust manifold today. Its a decat, so what do i do about the lambda sensor which should sit after the cat?
    Do i leave the blanking plug on the mani and and put the sensor somewhere where it breathes fresh air?

    Cheers

    Tie the sensor behind the passenger light ideally in a sleeve.
