How many catalytic converters does a 4 cylinder Ford Contour have?

Answer 1

Only one - and it is a real b----h to replace! Odds are, you'll have to cut the old bolts with a torch to remove the old converter. Also, if you need to replace the converter, I strongly recommend you also replace the O2 sensor. If the converter is fouled and not functioning, you can pretty well figure the O2 sensor is as well.
