Is your car shaking like a leaf in the wind every time you start it? Don't worry, you're not alone. A shaky car at startup can be alarming and frustrating, but before you panic and take it to the mechanic, there are some common culprits that could be causing this issue. In this blog post, we'll explore these possible causes and give you tips on how to address them. So buckle up and let's get started!
Introduction
If your car is shaking at startup, it could be due to a variety of different factors. The most common culprits are low engine oil, worn spark plugs, or a loose engine belt.
Low engine oil is one of the most common reasons why a Car shakes when starting then runs fine. If your engine oil is low, it can cause your engine to misfire and produce a lot of vibration. To fix this, simply add more oil to your engine.
Worn spark plugs can also cause your car to shake at startup. Spark plugs are responsible for igniting the air/fuel mixture in your engine, so if they're worn out, it can cause your engine to run rough and produce a lot of vibration. Replacing your spark plugs should fix the problem.
A loose engine belt can also cause your car to shake at startup. The engine belt is responsible for driving all of the accessories in your car (e.g. alternator, water pump, etc.), so if it's loose, it can cause those accessories to operate improperly and produce a lot of vibration. Tightening or replacing the belt should fix the problem.
