ive been dealing with this little piss ass problem for like 2 weeks now, i got a cel and ran the obd2 test to find i needed a O2 upstream sensor in bank 1(back of he engine). now i looked at all the 4 O2 sensors and they all look the same harness wise. now the back one on the engine looks like a extreme ***** to get to. i bought the motorcarft replacement online for 75 bucks(as oppsed to 130 at the dealership) and the harness looks different from the stock. has anyone replaced this sensor, and when you did, did the replacment harness body look any differnt than from the stock one? i went to three diffrent places, all with the same part, so its got to be the right part, but the housing looks different, before i try getting to it, anyone know what im talking about???
