my car just failed m.o.t on lambda high reading at fast idle
i replaced lambda sensor with a new one.
the car still failed, the sensor i took off was part no.90411959
but that sensor according to Vauxhall was the wrong one!!!
i have put the correct one on but it still fails fast idle lambda at mot station
can anyone help??
do i have the right sensor? which one do i use?
is there something else wrong?
my car is a 2.0 16v ecotec 1995
