   Hi guys. Just wondering if anyone knows if my car will pass the emissions test if i put a lambda sensor on. I have a straight thru supersprint exhaust and raceland manifold. The tester said all i would need is a lambda sensor and it should pass but i said ide probably need a standard exhaust and he told me not to.
   
   My emissions were 2.22 over the max 0.30

   plug a lambda in, unplug the battery for around 3hours or so, and then start here back up and retest it.
   
   I presume you have a cat though ?

    u WILL need a cat to pass an mot! lol its illegal to not have a cat lol i wouldnt even bother getting out of bed on the day of the mot if you dont have a cat or lambda sensor and i was talking about the lambda sensor in my last post
    
    also why dont you have a lambda sensor in the manifold? all you have to do is take it out the old oem manifold and screw it in to your new one,

    your car would not run right without a lambda sensor in anyway, you probably find when you fit a new lambda sensor your car will run much better and also be better on fuel

    the ecu will not be putting the right fuel/air mixture in, the lambda sensor just senses if the fuel is to lean or rich and the ecu adjusters it so it runs how it should, you will find it will run alot smoother when u fit a lambda sensor

    ye i will fit one soon, it is a little lumpy on idle sometimes at traffic lights and i need to give it a little rev and it settles its self out, and my mpg seams about the same as other vts owners so would be awesome if it did save me some fuel
