what lambda sensor?
 

Trying to work out what lambda sensor i need for my 1999 impreza turbo 2000 as it needs replacing tryed a few places incl subaru but all say differant codes and that i should have a pre and post cat sensors but havnt got cat and only one sensor at top of down pipe, please help if you can thanks

people are obviously getting confused with the new-age cars that have a pre & post cat sensor..........

classic cars only ever had ONE sensor although exact type and position depends on age/model

let me have your reg/ch number and i can sort a few options for you no problem
