Car backfires through the carburetor are sometimes caused by a lean air/fuel mixture. Backfires may also be caused by a leaking hose, faulty plugs or the brand of fuel being pumped in.Know More
Backfiring is a loud bang or explosive sound that occurs while the engine is idling down or shortly after the engine has been shut off. Most backfires through the carburetor arise as a result of faults within the ignition system. Fixing these faults is often enough to solve the problem.
Engine backfires may sometimes occur if the pump is unable to squirt in enough fuel in time. This may be because the pump is plugged up or simply not working. Changing the pump fixes the problem.
A faulty ignition system is a possible cause of a engine backfire. For engines to run efficiently, the spark plugs have to ignite the air and fuel at the right time. Incorrect timing can lead to the fuel being ignited before the manifold intake valve closes, causing a backfire through the carburetor or exhaust.
Holes in the pipe leading to intake manifold may result in an increase inflow of air, which unbalances the air-fuel mixture ratio. A leaner ratio is more volatile, and more likely to cause backfires.Learn more about Car Parts & Maintenance
A car that starts up initially but dies immediately thereafter is experiencing a problem with either its carburetor or fuel injection system. The culprit depends on the year, make and model of the vehicle in question. Carburetors are easy to fix, while fuel injection issues cost a large sum to diagnose and repair.Full Answer >
Superior Car Talk explains that a sputtering and backfiring problem is usually the result of moisture condensation in the fuel system. While the fuel tank may be tightly capped, water can still seep in over time as the result of temperature extremes.Full Answer >
Most car battery explosions are caused by thermal runaway, which is when the battery overheats, causing its cells to break open. Usually, one cell starts a chain reaction in which other cells rupture. A swollen battery is a less serious manifestation of the thermal runaway effect.Full Answer >
Coolant leaks and engine overheating are usually caused by a failing water pump. Automotive water pumps are designed to leak coolant through weep ports as a warning that they are failing. Aside from overheating, a distinctive grinding or whining noise caused by a bad bearing is also a symptom of a bad pump.Full Answer >
