alfa 155 1.8ts 8v, very bad emissions test, help please
Discussion
my newly acuired 155 has failed her MOT spectacularly on her emissions this morning, readings are as follows
CO max 0.30% - actual 3.63% (run 1)
3.52% (run 2)
HC max 200ppm actual 211 ppm (run 1)
259 ppm (run 2)
Lambda 0.97-1.03 0.90
0.91
and on idle
co max 0.50% actual 5.10%
now, although i can take a car apart and rebuild it etc, other than replacing service items (just got a mate with a garage to order new plugs (8), oil filter, oil, air filter and lambda) other than the cat what else could it be thats making the results so god damn awful?
would appreciate your thoughts and inputs
