Hi, my car has seen a noticeable drop in MPG rating so I hooked up my scan tool to track my STFT 1 percentage.
The range from highest to lowest was from +7% to -18%.
Is this normal for my car?
Also, my o2 sensor had a consistent voltage of8% so I tried to induce a lean response by pulling the PCV valve, and no change.
Someone told me that Accords do not have o2 sensors but have AF sensors instead and you cannot test it using voltages. Also, pulling a PCV valve on a MAP based vehicle will not cause the car to run lean. Is this true?
Thank you!
