Re: Check engine light
I searched that code on contour.org relating to a zetec. In addition to the dirty MAF and O2 sensors, it looks like it could be caused by a vacuum leak.

Re: Check engine light
First clean the MAF censor.

It could be a very small vacuum leak, perhaps around the pcv system or somewhere after the MAF. somehow, i bet unmetered air is getting into the engine so its not being picked up by the MAF and its running lean.
