So my 99 AGU failed on emissions ( and a couple of easy fixes) but i need some advice please.
C0 0.534
lambda 1.049
second fast idle test was slightly higher on both.
how can i tell if cat/lambda needs replaced ? would running the test without warming car up yield those results ? any other advice greatly appreciate. Car has done 101k and was serviced in march. Cotton air filer installed.

Have you scanned it for codes.
-
will it flag up much being agu with no EM light ?
-
Agu still stores fault codes the same as any other car, it just doesn't have an annoying light to tell you that something is wrong
-
If you scan it for codes and it is one of the lambda sensors you should get a 17521 code I think it is from memory.

right got the emission passed now thankfully , but still failing on the bloody handbrake :( new discs/pads , calipers rebuilt etc , i think one of the cables is stretched. ECP list 2 different length for my car though ????
