   recently brought a vtr and its got a 4-2-1 and straight through powerflow exhaust and it uses alot of fuel i think its over fueling loadss, 15pounds got me bout 40miles :/ and seems to smoke on idle and reving black smoke and smells really strong of petrol, it hasnt got a cat in so obviously going to smell of fuel but not that bad, any ideas?

   lol he cant be an eco driver if hes getting 23mpg in a saxo. just drive sensible dont go over 3k revs obviously unless you're joining a motorway or carraigeway, keep tyres at right psi, anticipate whats going to happen ahead and come off the accelerator instead of braking to a stop

    It's got one lambda sensor in the manifold the other one i don't know what the guy did before :/ reckon that's the one I need in? Also proper sounds cammed at times coz lumpy idle so guessing over fueling doing that too, so I'm gonna service it 2day what you reckon to the 2nd lambda? Cheers Joe

    Put 2nd lambda secured to somewhere underneath the car outside the exhaust so it's reading clean air

    If hes plugged the second O2 sensor into the manifold it will be over fuelling iirc
