2000 Ford Windstar SE that has "ch. engine" light on 6 mos. Just got reject.-codes P0171, P0174. How can I fix this myself?
Google the codes, and you will get information about them. I did that, to start you off - it's lean mixture. Here's a link - http://repairpal.com/OBD-II-Code-P0171-and-P0174
In my opinion,to fix this this kind of problem requires skills and experience in maintenance of ford. These codes need technical and mechanical ideas to deal with them. I would suggest that you consult your mechanic for more professional help.
Unfortunately it requires some money to keep a car running.
