Please help I am in urgent need for a lambda sensor for a 94-95 wrx!!! preferably new, any help on where I can get one will be gratefully appreciated. Thanx

 

I'm currently having the same problem. Try

 

Failed emmissons test, gararge are servicing the car tomorrow with a view to changing it when I find out which one I need.
I posted a similar thread & one reply stated that on early cars this is a weakness.

Let me know how you get on ie the cost etc

 

i had rediculously low fuel consumption therefor had the emmisions tested. The co2 was 6.89% it should be < 0.30%. Had a subaru code machine pluged in which showed the lambda sensor fault. How did you find out about yours failing?
