my 2002 ford e150 runs extremely rough on a cold engine. After warming up, it does quite a bit better, but still a little rough. Check engine light is on, and O'reilly's says it is the code for 02 sensor. Should I trust this as being the o2sensor? If so, how easy is it to fget to; I think they said it was bank 1. Thank you!!

Hello and thanks for donating


A failed oxygen sensor will rarely cause a rough idle issue, although a clogged catalytic converter will cause this issue and will also throw the oxygen sensor trouble code. I would suggest having the cat. converter flow tested as well as replacing the oxygen sensors. They are part of regular maintenance anyway and are not difficult to replace.
