[Solved] Clogged/Failing Fuel Filter/Pump and Fuel Trims
Can you tell me if my statement below is correct? This is for cars in general so not specific to any one vehicle. Here it goes:
A very high percentage, positive fuel trim (%) does not mean I necessarily have an issue with the fuel filter/fuel pump. However, if there is an issue with the fuel filter/fuel pump it will always show as a very high percentage, positive fuel trim (%).
Wouldn’t that for sure result in high fuel trim values?
no I wouldn't say "for sure"
what if fuel pressure is able to keep up 90% of the time, until you really start getting into the pedal?
