Question about 2001 Ford Expedition
Mileage has slipped since we first got our expedition.Have changed plugs, coils,and air filter. Was wondering if the catalatic converters would be getting plugged(has 180000km).Also could the O2 sensors be going. What would happen if I gutted the catalatic converters.
Thank you HM
If you gutted the cats it would emit a lot of bad emissions and a check engine light would definitely come on. I would try to clean the mass air flow sensor.
