what’s the cause of my car burning gas?

car tuning

what causes a car to burn alot gas, does it have anything to do with the engine being old or what?

i have a ’97 honda civic, and for some reason when i accelerate my car seems to slow down whe i don’t press on the brake pedal like soemthing is holding it from picking up speed but after about a couple of seconds the car jerks somewhat and then it back to normal so i don’t know what this could me whether i need a new engine or just a tune up
so any suggestions?

    What your car likely needs is something in between a tuneup and a new engine.

    Most likely some sensor is malfunctioning, and it is causing the air/fuel mixture to be way too rich, i.e. too much fuel.

    Do all of the simple things first:
    Change the plugs
    Change the air filter
    Have the timing checked

    if you are under 150,000 miles then you will get a free tune up from honda. just go to a dealer and tell them you are there for the emissions extention. if the check engine light is on, and it is something that could affect the emissions then it will be covered. just go to your local honda dealer. all 1997 honda’s are under a warrenty from honda for 150,000 miles.

    i always say its the oil. or tune up in general.
    #1 older the car thicker the oil. if you want better mileage go with a thicker weight of oil and try synthetic or hight mileage oil. instead of th 5w 30 that you putting in this car. this is a 97 honda at it has a timing belt that set on the water pump this could need to be changed, however this car is older so im pretty sure that this has been changed before or soon will be. and when changing out the water pump on a honda you should always change the timing belt with it.

    Sounds like it’s starving for gas. Possibly dirty fuel filter or an injector issue. I’d change the fuel filter, especially if you’ve never done it. Then spray some throttle body cleaner in the throttle body or at least run some injector cleaner in your next tank of gas.

    This could be a TPS (throttle position sensor) problem. If there is a dead spot in it it after idle, it will suddenly think it’s in idle, with a throttle plate partially open, which will confuse other sensors.
