Question about Ford Explorer Sport
I had a major tune up last week but ''check engine'' light still came back on, The tune up of new plugs & wires and the usual stuff included replacing the intake manifold gasket. Clearing the Mass Airflow & filter change. Flushing the fuel injectors replacing fuel filter and replacing burnt out ''check engine light. ( $1000 out of pocket)
Initally there were 4 codes. Now there are 6 codes.
The codes are telling me:
P0171 System to Lean Bank 1 P0174 System to Lean Bank 2
P1131 Lack of H02 SII - Sensor Lean
P1136 Sensor Indicates Lean - Bank 1
P1151 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank 2 P1156 Sensor Indicates Lean - Bank 2
When starting it it idles rough for about 30 seconds but then stablizes at about 800 to 900 rpm. While driving, it runs great no misses or loss of power that I can detect. Will the sensors affect the fuel/air flow mix or could this be a fuel pump problem? Why would there be ''lack of hydrocarbons?'' Help????
I hate to tell you this but it sounds like a computer issue like it is bad. Your codes are basiucally telling you that all your sensors are bad at the same time very rare in any vehicle
