- 05 Explorer 4.0 Flex
I was hoping someone can help me out. My 2005 Ford Explorer, 4.0 Flex Fuel, 4WD with 76000 miles has an "Service Engine Soon light on". Hand held scanners are reading P0172 and P0175 Bank 1 and 2 to rich. I replaced the MAF filter with no change. I brought it by my service station who hooked it up to the diag machine and all sensors look fine. They recommended a Fuel Injection flushing\cleaning service based on the milage of the car which I had them do. I also performed a tune up (Air and Fuel Filter, PCV, Plugs and wires). I had the codes cleared evrytime something was attempted but the light is still comming on. I've read somwhere that P0172 and P0175 are caused by a ether a bad MAF or a Fuel pressure regulater. Throughout all this the car has been running fine with no hard starting hot or cold. Can anyone help me out.
