i have a 99 ford windstar with about 67,000 miles, and the check engine light is on all the time. I had it diagnosed and got a P0171, P174 [ system too lean [Bank 1 &2]. Erased the codes and they returned in less than one day of driving. Can anyone help me on this and trouble shoot. Any help will be much appreciated. Thank you.
