Question

My 2001 Ford Explorer Sport Trac has loss of power, misfiring, and stalls. I also got the engine codes P0300 and P0174

Answer 1

Hi there,

The P0174 code means there is a lean fuel mixture on bank 2 of the engine. This can cause the multiple cylinder misfire codes as well. Usually this is caused by either a bad mass air flow sensor or intake manifold gasket leak on this engine.

Answer 2

P0174 FORD Code - Fuel Injection System Too Lean Bank 2
