Setting a fuel ratio of the engine that is not appropriate to make the mixture into "fat". Called "fat" because the supply of fuel into the combustion chamber is greater than required.
Beware if your car's engine started to feel unstable at idle position. Unstable engine means setting the fuel and air mixture in the engine not quite fit. Such conditions can cause fuel consumption to be more extravagant.
Tips for your car! Machine is unstable when it's Idle, making extravagant Fuel
An unstable machine can be seen from the position of the engine RPM up and down. Supposedly, after the ignition is turned to START position and engine life, RPM remains stable when we leave on the gas pedal (idle).
In addition to fuel consumption resulting in a more extravagant, the machine is not stable in the idle position is likely to menmgakibatkan engine suddenly died when the car was driven on the road.
Another way to know the arrangement of fuel and air mixture is not right, is through exhaust gas emission test. When test results are listed on the paper HC and CO levels are too high, meaning the fuel into the combustion chamber is too large.
The solution is simple. Lives rearranged ratio of fuel and air mixture in the vehicle, through the examination and adjustment of the ratio of fuel and air are burned, or often called CO set.
Nevertheless, it is quite possible if adjustment is just right but still incomplete combustion of fuel. To be sure, do check the throttle body. Most likely this component of the flow of dirty air and disrupt the smooth flow of air into the combustion chamber.
In addition, check the ignition system. Perhaps there is a dead spark plugs, coil worn or prisoners on ignition spark plug wires are too high.
