SOURCE: 2002 6 cylinder 3.o engine Ford Ranger. Cold start

Changed the air filter lately? Possibly defective O2 sensors, but I doubt it. If air filter and intake are clear, I'd check barometric pressure sensor and mass air flow sensors. Get a Haynes or Chilton's for $25 at Pep Boys for instructions on testing these componenets

I have a 1997 1500 with a 5.0 Im getting codes po143 po172 po175 and po300. Im not sure what the cause could be.
Code 300 is for a random miss.
172 and 175 are for the same problem - 172 is for a rich fuel mixture bank one and 175 is for the fuel mixture too rich on bank two.
Code 143 is for a rich mixture for sensor number 3.
All of the codes could be connected to a leaking injector or other fuel problem. Very seldom are all of the O2 sensors faulty at the same time.

Want to know what PO172 System too rich bank 1 means and PO175 System too rich bank 2 means. These are fault codes from an emissions test I had done on my Dodge avenger and it failed
it means your cars computer is pumping too muchgas into your motor because it thinks the engine is either running lean possibly due to faulty o2 sensors or that the coolant temp sensor is giving false readings and the ecm thinks the car is still too cold.
