Question
hi kevin my 97 sebring has a rough idle feels like its choking itself had it on the computer and it said cylinder 5 misfire,fuel too rich, and o2 censor2 bank one im not sure what to do could it be the injector have replaced spark plug wires throttle position censor please help

Answer
Hi Alan,
I would start by checking the wiring to the downstream oxygen sensor (after the converter) and if that looks OK then replace the sensor. Then disconnect the battery briefly to erase the codes, drive it for a while, and if the idle is still bad and the codes still says too rich and #5 misfire, then the #5 injector is suspect. Although there are a great number of possibilities for misfire, that too rich points at the injector.
