My son's Sport Trac has the following error codes: PO171 and PO174. Anybody able to assist in identifying the cause? The breakout (based on the Autozone tester) said "System too lean"
69800 miles on the V-6 4.0 2WD Check engine light came on when stuck in a Florida Interstate traffic jam (1 1/2 hour at a crawl). Is there a way to clear the check lite to see if the fault comes back?Thanks
Jack
