97 Strat - Upstream O2 sensor location
Can anyone tell me where the upstream oxygen sensor is located on a 97 Dodge Stratus? I am getting error code 21 and I have changed my downstream sensor - found it without much difficulty. Does the upstream one look identical to the downstream? I see some sort of sensor in one of the 4 pipes coming off the engine block (the exhaust manifold) but it looks very different from the downstream sensor - oblong looking with a couple of screws that hold it in rather than the sensor bolting itself in.
Gotta get this to pass CT emissions!
TIA

RE: 97 Strat - Upstream O2 sensor location
Can't believe no one has had to replace that. OK, I'll answer myself (for the benefit of others) as I found out the location. It is in the back of the engine where the manifold comes out. Looks almost inaccessible or very tough to get any kind of leverage on a wrench to remove it. Anyway, I am going to try to access it from the top rather than from underneath.
