I have a 1996 9000 CS and from time to time my check engine light will come on and I got the code checked out and it says it's the oxygen sensor. I have also been getting about 6 or 7 miles per gallon less than I normally do so I think it's time I change them.
Is there anyway to tell whether it is the oxygen sensor that is before or after the catalytic converter or is it best to just change both of them? Does anybody have any experience with the universal ones that require splicing or is it worth the extra money to just get the ones that fit and plug right in? I've had good experience with http://www.thesaabsite.com/9000/9000fuelsystem.htm so I was just thinking of buying from them. It would cost me about $130 for both sensors from that site so it's not tooooo bad.
Also, is there any trick to getting these suckers out? I tried getting the one that is before the catalytic converter out and I couldn't even get the thing to budge. And lastly, is there an easier way to get at the place where the wires plug in or is reaching around and just feeling for it the best way? Thanks for any help!
