Question

What do these codes mean and how do I fix it?

Answer 1

P0172  Fuel trim too rich (Bank 1)

P0175 Fuel trim too rich (Bank 2)

This mean there is more fuel being use than required, a plugged air filter will cause this code condition and even low coolant level can cause these code condition , the worste case scenerio would be a mechanical condition such as low compression .
