Ford zx5 engine problems - The Ford Focus Forum

**Spieler_89** · 11-04-2009, 11:59 AM

I have a 2003 zx5 with the ztech engine. The check engine light came on the other day and for a while its been having idle problems and lacking power towards 3rd and 4th gear(skipping from the misfire on 4). So anyway, i went up to advanced and had the light tested, it was throwing a p0304, believe thats the misfire on cylinder 4, and a p0316, misfire first 1000 revs. I looked online at this webiste to see details on these codes, but not to sure what exactly i should do.

Does anyone have any suggestions on this?

Thanks,

Joe
