If a car is sputtering when you try to accelerate, this indicates that it is time for a tune-up. A full tune-up of the engine is in order, rather than only swapping out the spark plugs. Ignition misfire is one of the symptoms that the engine is in need of some help; the sputtering is a sign of bad timing that also causes damage to other engine components.Know More
When performing a tune-up on a car, check the entire secondary ignition system. This includes the ignition coil, rotor, cap, wires and plugs; some mechanics recommend a PCV valve as well.
If the tune-up does not solve the problem, air intake is another (although much less common) possibility. Look at the intake hose for cracks because if the system is not airtight and a car has a mass air flow sensor, sputtering at acceleration is one possible sign. Repair any air leaks that are present and then test the engine again. The reason why air leaks cause sputtering is that the air-to-fuel ratio is hampering the performance of the engine. For the best results, take the car to a shop, and then inform the mechanic all of the steps taken so far.Learn More
As a general rule, putting a lift kit and bigger tires on a truck will decrease its gas mileage. There are, however, some ways to mitigate this.Full Answer >
A lithium-ion car battery powers hybrid and electric cars. Lithium-ion car batteries provide an automobile technology that improves the environmental efficiency of cars. This type of battery is useful for green driving and helps electric cars travel up to 250 miles without burning gasoline.Full Answer >
While it may seem intuitive that more expensive gas is the better choice for any car or truck, the reality is that the best gasoline for any vehicle is the one specified in the owner's manual. Paying more for a higher octane may not produce any benefits at all.Full Answer >
Most cars have a throttle position sensor, manifold pressure sensor, engine coolant temperature sensor, mass air flow sensor, camshaft and crankshaft position sensors and a oxygen sensor. Automobiles also have detonation sensors, EGR sensors and intake air temperature sensors.Full Answer >
