Post by: mick-1975 on 25 July 2013, 15:06:32

hi all ive noticed that while the car is running i can smell rich fuel at the rear of the car and under bonnet.
 i ahve noticed that the exhaust manifold has a crack in it which needs replacing .

Mine was running rich when the wires to the lambda where ripped of, so either that, or the lambda could be broken.. It can also be something simple as a cloged airfilter
