because of ignition coil faulty.due to mountings,abnormal fuel pressure.
One of the main causes of feeling a vibration in the gas pedal is engine vibration. The vibration from the engine causes the accelerator cable or linkage to vibrate and the vibration can be felt in the gas pedal. Check with a mechanic to be sure.
Engine vibration can be an indication of a misfire, but more often it's just the AC compressor causing a little shaking.
No. It only senses engine vibration/knock.
there may be leakage in your coolant water cap at the time of starting vibration causes water to escape from it entering in to the engine causes white smoke
This depends on a few things: If your vibration is happening at high speeds, get your wheel balance/roundness checked if this is happening at all speeds, check your alignment/steering if this is happening when slowing down, chances are that you need new brakes
a weak battery will not cause an engine vibration.
During acceleration? I'm not sure. But when both idling and acceleration the engine's combustion can cause a lot of vibration in the steering wheel if you are in an older vehicle.
Possibly an umbrella wrapped around the flywheel?
not enough oil in the engine.
You eating the engine.
Timing needs adjustment is the most likely cause.
Excessive engine vibration can because by and engine that needs to be tuned up. The vibration can also because by worn out motor mounts.
