Engine Performance problem
1998 Vauxhall Vectra 6 cyl Manual
hi I took my vectra sri for a mot the other day and it failed on emissions I replaced the cat as the mechanic done a test on it and said there wasnt one there.
i also replaced the lambda sensor.
i had another mechanic with a diagnostic who ran a test and said all the sensors were fine and running as they should.
i went back to the garage again and got a reading printed off and they are as follows
any ideas what it could be I am completly stuck now
