Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another.
Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings.......................................................All of the above and possibly more.
Contaminated fuel could cause a misfire.
Depending on the cause of the misfire, it could damage the catalytic converter.
Yes they can, if one or more are either stuck open or not working at all it will cause a misfire.
Anything that could cause a cylinder misfire can cause the check engine light to flash. A restricted fuel filter is one.Anything that could cause a cylinder misfire can cause the check engine light to flash. A restricted fuel filter is one.
It could.
No it will not cause misfire.
It could, depending on the cause of the misfire.
can low grade gas cause a misfire, I don't think so but, Contaminated (water, etc) gasoline could. Flow restriction (plugged fuel filter, plugged fuel injector) could. Incorrect fuel pressure could.
I have a 95, had a misfire... mine was because of the plug wires... changed the wires and plugs mis fire stopped...
If you have a "check engine" light on, start with having the codes read. A misfire code can tell you which cylinder or cylinders are having problems. A misfire could be the cause of your engine vibration.
Yes, if the wire is old and frayed or if it is rubbing against metal the wire could ground out and discharge into the engine block before it get to the spark plug causing the plug to misfire. If the contacts are worn or loose you could also get an intermittent misfire.
Do a proper diagnosis to figure out the cause of the misfire, then repair it.
