Typically spark plugs just wear out over time. However, over heating the engine or having oil on the spark plugs can cause early blowout. New spark plugs can be bought at any automotive parts store and installed by your mechanic.
Not likely. Smoke from under the hood denotes a leak. Either your coolant or oil is leaking. White, thick smoke is oil. Could just be a gasket. Thinner hazy smoke is coolant. Check your hoses. Look for fluids/wet spots. Bad plugs can missfire, and make your exhaust smoke.
Balck smoke usually means the engine is burning rich - that is to say, more fuel is being delivered to the combustion chamber than can be ignited by the spark plugs. Keeping a good tuneup schedule and clean-up/replacement of sprak plugs will prevent, or at least minimize the black smoke under heavy acceleration.
When changing the spark plugs of a car, it is important to remember to gap the spark plugs. The gap for this cars spark plugs are 0.051 inches.
A Toyota Allion has 4 spark plugs. These spark plugs are not hard to replace, and can be found in the engine, under the hood. After 2008 models, they are harder to replace.
Spark Plugs do not affect your alternator. As long as your engine is running then it should be charging unless your alternator is bad
Check your battery and alternator.
They are part oft he electrical system. The alternator is driven round and round by the fan belt, and when turning generates 12 volts that charges the battery AND feeds back through the wiring harness to the distributer, which feeds the spark plugs, which fire the engine. Once a motor vehicle starts ( using the battery as the power source) the alternator essentially drives the spark plugs to run the motor to turn the belts to drive the alternator to provide power to the spark plugs.... and, and, and...
you can check the alternator or the timming jumped
Bad spark plugs, spark plugs wires, etc.
There could be so many problems. Batery, starter, alternator, serpentine belt, no spark... the list is endless. spark plugs? spark plugs?
Bad spark plugs and leads can commonly make the engine feel like its 'hesitating' or skipping a beat, often worsening in the higher rev range. However it is not the cause of white smoke. White smoke is typically associated with coolant getting into the combustion chamber. The most common cause of this is a cracked head gasket, which you will need to replace in order to rectify the white smoke.
No, but burning oil will give you bad spark plugs.
you are not getting spark. this could be from a bad alternator, bad spark plugs, bad spark plug wires, or bad engine coils. The spark plugs and wires are the cheapest so try putting in new ones of those first.
This could be bad spark plugs or plug wires
Not likely sounds like a blown head gasket
