2003 Ford Explorer 6 cyl Automatic 90'000 miles
I recently installed a K&N filter and intake tube on explorer. Shortly after, check engine light came on. I checked the codes with hand held OBD reader and found codes 171 & 174. System to lean- Bank 1 or 2. After erasing the codes, to allow for the computer to re-set ( the instal directions stated ) the same codes are coming back every 2 or 3 weeks. The vehicle runs great otherwise and the new filter has improved power and mileage. I sure hope you can help me eliminate this anoying CE light?
