What is an engine is shaking, pulsating, or vibrating inspection?

If you notice that your car’s engine is shaking, pulsating, or vibrating, your mechanic should perform the necessary inspection.
While this issue requires immediate attention, some of the reasons behind it might be normal— like needing to replace the spark plugs. On the other hand, some causes may be more serious or elude to something larger and costlier, like a broken engine mount.

There may be several reasons as to why this is happening. Though, it is most likely one of the following reasons:
  • Old and worn spark plugs and wires. This is the most common reason and the first thing a mechanic will inspect
  • Loose or disconnected hoses on and around the engine
  • Loose connections at the positive and negative battery terminals
  • Very dirty or clogged air filters can also cause your engine to underperform
  • Loose timing belts
Since there are several potential reasons behind an engine shaking, pulsating, or vibrating, it’s best left to a professional to determine what is wrong.
