Can anyone tell me exactly where the O2sensors are located on a 2000 Suburban? I know that there are 4 I'm just not sure where they all are.

Thanks

one should be somewhere around the exhaust downpipe from the exhaust headers and there's probably another 2 behind the catalytic converters. I didn't even realize that the newer burbs have 4. AFAIK, my 91 only has one...
