As I explained all feeds check out. Both on running and not running tests values are proper. Can you give me any other advise? Please respond to my email address (dcole11@cox.net) As your system would not recognize me I had to enter another email to get the question in,(chezgigi@rock.com)
Thank You Don Cole -dcole11@cox.net

Sorry, but we do not respond directly through e-mail.


You question is not real clear and you didn't post code numbers as you should have but i expect you have PO171 and PO174. This is a common combination on Fords and is usually caused by a severe vacuum leak. They are notorious for sucking holes through the rubber connectors for the large vacuum supplies like the PCV and brake booster. Listen for a hissing noise when idling and try to follow it to it's source.
