Check your tire presure. Also your O2 sensor could be going bad.

Burning much gas


A lot of things can cause a car to burn more gas. A clogged fuel filter, bad spark plugs and spark plug wires. Also a clogged O2 sensor will cause the engine to work harder reducing fuel mileage. Perform a complete tune up, replace the spark plugs and wires, replace the fuel filter and air filter.

I HAVE A 2003 KIA SORENTO LX & IT IS USING TO MUCH GAS LATELY>>>HOW WILL I KNOW IF I NEED MY FUEL PUMP REPLACED? WHERE IS THE PCV VALVE LOCATED?


the fuel pump will not cause bad gas mileage.the spark plugs may need changing,fuel filter,air filter,plug wires(basically a tune-up),or the thermostat probably needs changing as this can cause poor gas mileage as it won`t allow the motor to get to proper operating temperature(computer monitors temp)and commands fuel injectors on longer(spray more fuel).driving habits change over time look at this also.cold whether driving also will use more fuel.pcv valve i can`t help you,maybe a parts store will show were it is if it has one.the only time you change the fuel pump is when it gets noisy or it quits altogether,or the pressure is good but the fuel volume is not to specs.

My car is using more gas than usual why?


1st , i would start the car up and make sure you don't have a fuel leak around the fuel tank area or where the fuel filter is, also how long has it been since the spark plugs have been replaced, and air filter, these items have a negative effect on fuel mileage.

How to give a tune up for a 1990 toyota 4runner?


with many new modern fuel injected vehicles its hard to give them a tune up without plugging them into a computer or getting an aftermarket computer chip and programmer.

however, if your toyota is running a little rough and getting bad gas mileage i would reccomend a new set of spark plugs and wires. and maybe a new fuel filter, i would do the spark plugs first, if the results are not satisfactory then change the spark plug wires, and if the results are still not up to your standards comparing the way it used to run to how it runs now then change the fuel filter. doing all these things will make the vehicle run clean and efficient like it should. and if it doesnt than im sure you have a vacum or oxygen sensor problem.

just wanna hop up the performance a little bit and get better fuel mileage?
then i would suggest and personally recommend a complete K&N cold air intake kit.

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.

NOT GETTING GOOD GAS MILEAGE


here are a couple of different problems that will cause bad fuel mileage. first is air filter, still getting low mpg. then the pcv valve. clean fuel system. the cost of filter about $20 pcv was $12 and the fuel system cleaning and pcv is easy to do. when cleaning the fuel system,clean the injectors the fuel rail and the throttle body be sure that you have them change the oil or that you do it after they work on it. Notice whether the oil smelled like fuel then your engine needs platinum plugs for best spark they can run as much as $8 each.

Seems to be burning more gas on the mileage


try a tune up. When is the last time you have replaced the spark plugs, wires, fuel filter etc...? all these things can worsen your fuel mileage if they are not changed like the should. Along with a dirty air filter.

2006 Toyota Tacoma Low Mileage or Not...Spark Plug Life


24 mpg on the highway is actually pretty good for that truck. at 48000 miles and being 3 years old its time for plugs, air filter, and fuel filter if available. thats cheap maintenance for now. but if very self conscious, run some fuel injector cleaner first, then change the plugs, because any octane booster or fuel injector cleaner can run the risk of fouling out a plug, by creating a hotter spark then what, normal gas does. the burn is hotter.

Jeep liberty gas mileage


when was the last time you put in fuel injector cleaner? I put in Lucas Oil Injector cleaner every other or every oil change.

There are alot of factors affecting your gas mileage. Tire wear, tire pressure, wheel alignment, air filter, fuel filter, spark plugs, oxygen sensors, just to name a few. So to say what you need is just shooting in the dark without more information. I would probably start with your oxygen sensors, and then perform a tuneup. If your vehicle pulls to one side or the other when driving on the highway you need to stop into the shop for a wheel alignment.
