01 expedition fuel mileage

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.

My 2000 ford expedition stalls when i get up to speed... I have changed all spark plugs and changed a coil that the auto parts store said to on number 7 and i still have the same problem with the stalling...


This can only be a guess since I don't have the mileage. Around a 100k on the odometer and fuel filter never changed..
No filter then the screen on the fuel pump inside the tank.

I have a 2008 Saturn Vue XE AWD 6 cylinder that is only getting about 19mpg highway miles. Does anyone have similar problems and wondering if it is something that can be done to improve this. Thanks!


You can change the spark plugs and coils, wires for a little better gas mileage. I would say 60,000-70,000 miles. If you are under that, probably still ok. You can try fuel injector cleaner in the tank. Check your tires and make sure they are properly filled up. If the vehicle is out of alignment, it will cause bad gas mileage. Make sure you have no vacuum leaks and make sure your air filter is clear. If you have any questions, just let me know.

Getting very poor mileage - wondering if there is a sensor that needs to be changed?


The 02 sensor near the firewall would help. Change your plugs, fuel filter, and air filter.

Does the fuel filter affect gas mileage


there are lots of things that can affect gas mileage. if the spark plugs and wires are worn out, the air filter being dirty, dirty fuel filter, proper inflation of the tires, O2 sensors that are contaminated and performing poorly. the first thing to do would be that the engine is in good working order, as in no check engine light, no misfire, etc. a poorly running engine will put out terrible gas mileage. then you can start with the things i listed.

Usually when it comes to bad gas mileage, an air filter change, fresh oil and filter, fuel filter and making sure you have no vacuum leaks....

Also, believe it or not, improper tire pressure will affect your gas mileage.

New spark plugs and wires are a "nicety" but if there is not damage to them, then they will be fine.

Location of the PVC and gas filter on 4 cylinder 2003 Solara


The PCV and the fuel filter replacements are not going to increase you fuel mileage. What you should really consider is getting some good fuel injection cleaner into the tank, and get an "induction system cleaning". Those two items alone will address most of your mileage issues. The PCV does nothing for mileage, nor does the fuel filter. Also, for maximum fuel mileage, you should have the correct sparkplugs from Toyota in your car. "Aftermarket" plugs doe not perform very well at all.
