[Stupink]

Is it actually running too lean? does the code come up on driving or idle too?

[warby]

spark plugs are black n when code turns up its there when drivin or idle n usng a lot a fuel code cames n goes cant work it out

[Stupink]

black is too rich not too lean.
are you sure the new lambda sensor works ok? fault code didnt start appearing after you installed it by any chance?

[warby]

i no thats wots doin my nut there black but code says 44, fitted it a couple of months ago only just started playin up a wk or so ago was code 13 got rid of that now its keeps sayin 44 could the lambda be playin up

[Stupink]

get the sensor checked, look at topbuzz.co.uk for info on testing yourself or take it to a garage with a box doobery to plug in.
