should be 2 down on the exhaust (1 ea side) near where the join is for the exhaust manifold and engine pipe flange is near the cats , maybe 2 more closer to the engine

theres 1 each side at the bottom of the exhaust manifolds/headers then 1 each side in your exhaust after where it connects to the cats, the front one's check/control your air fuel ratio and the second ones make sure your cats are working

Which ones could possibly affect the fuel efficiency ?
