As I was driving today, My Focus started hesitating slightly at low RMPs. The
RPMs were just high enough to maintain my speed. The hesitation seems to be at
speeds around 45 MPH and below. At least I didn't notice it at highway speeds.
A little later in the day, the emission system warning light came on. I am
thinking it might be the oxygen sensor, but I haven't had a chance to really
look into it, since it was the weekend and late in the evening.
Anyone have any experience with this before> Thanks in advance.
