Is there a smell of gasoline? My 95 accord had two spark plugs that failed or at least not firing correctly. Change plugs back to old plugs and the problem disappeared.

If you brought your car to Honda for service, they probably forgot to reset the maintenance reminder. If you took it to another shop, they probably did not know how to reset it. Anyway, the reset procedure is:

Put your key in the ignition
Turn the key to the II position for a couple of seconds
Then turn the key to the off position
Now push and hold in the odometer reset button
While still holding the odometer reset button, turn the key back to the II position
Hold for I think 10 seconds or so and your maintenance reminder light should reset it self.

SOURCE: 2000 kia sportage trouble code po171 once in

I have 2005 Kia Sportage with a check engine light. No other symptoms. I was told by Kia and Local mechanic that it is the fuel injectors. Error Code states that Fuel injectors are running lean. Put Master airflow- no change. Ran engine test with propane to run rich and trim never changed from 15. Car runs great. Kia dealer said that this is because we use Ethel in gas that it effects the alumium fuel rail delivery to the injectors and that it is necessary to change all of them .Kia Dealer wants $1,000.00 deposit to place order 6 fuel injectors from Kia. (Has anyone heard of that?)Also put fuel injector cleaner in tank.Does anyone have any suggestions before I spend over $1,000.00 to replace all 6 injectors or possible idea of what could be wrong?

I have a honda accord 1990 ex carburator vitesse engine f20A.. transformed to carburator automatic .but ihave a problem a slow acceleration and high fuel consumption how can i fix this 2 problems?

Check your timing belt, when I changed mine the pick up increased drastically and the mileage was increased. Remember though that any honda will do better if you do a more gradual increase in acceleration.

I have a 2005 honda accord and the fuel consumption is too high what is the cause and the solution to handle it.

The first thing is to check for fuel leaks and for restricted intake or exhaust and ensure the routine maintenance is up to date.

It is important to know what the current fuel consumption is in miles per gallon or km per litre. The modern trend of paying set amounts of money gives a wholly false impression of actual fuel consumption.

When checked accurately over a period and averaged to take account of different types of driving conditions, freezing temperatures and so forth, mostly the result is found to be not as bad as first imagined.

If all checks are found to be ok and the accurately checked consumption is still too high further checks will be needed.

A few possible faults are incorrect fuel pressures, bad injectors, incorrect valve timing, "tired" oxygen sensors, bad thermostat, "tired" temperature sensors...

Wheel alignment, tyre pressures and binding brakes can also be factors...

Causes of excessive fuel consumption in honda accord 2003

This is not easy, perhaps the fuel injectors are malfunctioning, computer input to them could be wrong, I'd get the fuel system checked.

What could be responsisible for high consumption of fuel

It would help if you gave more information, such as mileage on car, manual or automatic trans, condition of tires/brakes, but here goes anyway. Let's assume you have checked the basics such as tire air pressure, front end alignment, dragging brakes, anchor tied to the back bumper, and none of these are the cause.

Start with condition of exhaust system--bad converter, bad muffler, potato jammed up the tailpipe. Then check air filter, spark plugs/wires, but perhaps most likely is leaking fuel injectors. Does engine oil smell like gas? Next most likely is bad engine coolant temp sensor. Is check engine light on? Read the codes for codes if yes. Bad coolant sensor can be like having choke on all the time.

Bottom line is there are many things which contribute to good fuel mileage so having a good mechanic read real time data with a good scan tool (not the kind Auto Zone uses) will save $ in the long run. Good luck!

My 2000 model Nissan Sentra Ex saloon has high fuel consumption. What could be the cause?

The air filter will affect mileage if it hasn't been changed in a while. The injectors may be sending too much fuel either from wear or a map sensor problem.

Honda Civic 1.6 vtech Inspire 03 with poor fuel consumption

this car is fitted with a computer controlled engine/gearbox it will try to make you drive as economically as poss, if you let it,Try this,without using the gas padal let the car accelerate all the way to top gear on its own then from stop use 1/3rd of gas pedal upto top gear, try not to assist acceleration let it do its own thing.if you can drive like this all the time gas mileage will be considerably is made this way because makers have been told to reduce power/gas consumption in all cars....of course you can use kickdown but watch your fuel guage....

High gas mileage (15- 20 l per 100km)

try changing the oil also it will cause the engine to burn more fuel with bad oil because it gets hot and evaporates it alot more

High fuel consumption

Check the following things: air filter, wheel alignment, and timing belt, all of them if not serviced on time can affect your fuel consumption. I do not think its the heat because I drive my car in Phoenix AZ with temperatures comparable to Dubai and I still get 500+ km/tank.

Good Luck,
