IN ORDER TO HELP YOU IT WOULD HELP IF YOU PLEASE STOP YELLING and also for us to know exactly what, if any other symptoms your car has. Is your check engine light on? Are you getting really poor gas mileage? I believe if your engine temp sensor were failing, your CEL light would be on. I don't know where the engine temp sensor is located on your particular engine, but I can show you where on mine it is... also, I believe if you go to any auto parts store, they can help you too. It is a readily available part, VERY easy to replace, and not even expensive! (mine was $20 USD). I also believe there's only one on your engine (but don't take my word for that, I don't know your engine at all, I just know the other engines have only one)

Edit: see pic below for location. Gray part is electrical connector, brass part is the sensor itself. Just unscrews from the block.

it helps to know what all your gasses were. at least the 4 main ones: HC, CO, CO2, and O2. if you can provide that info, I can better help you.

It might also help if we lived somewhere that actually sold st202's. Cuuuuuz I don't know about you guys, but I don't know euro spec emissions that well.

did you let your car run as you waited in line? or was it stopped. let the cat get hot so it can work.

but as you said it wasn't cat related. so
