Hi, how many o2 sensors(lamber) as a subaru turbo 1999 got and where are they located.

thanks martin

 

just the one in the downpipe near where it bolts onto the turbo. Mt my97 wagon had another sensor after the down pipe cat, i beleive this was a temperature or "cat on fire" probe. I deleted it when i went to a sports cat as did not have anywhere to plug it in
