A car can end up shaking or vibrating excessively like there's an earthquake happening within it due to a brakes error, tire issues, or low-level transmission fluid. It could also be because of your axles, cylinder misfires, extreme weather, faulty engine mount, spark plug issues, and extreme weather.
Therefore, in order to fix your car engine vibration concerns, it's imperative that you get to the bottom of things and know what's causing all this shakiness in the first place.
The Multiple Ways to Fix Car Engine Vibration
- Spot the Source of the Problem: You need to find the source in order to fix any problem. If your cylinder is misfiring, causing your car to rumble like it's about to explode then check the diagnostic trouble codes on your OBD-II scanner. These codes will help you or your mechanic to determine which of your cylinders are misfiring. The misfiring can be caused by a malfunctioning computer, the air supply, the fuel supply, or the control sensors.
- Analyze The Problem Itself: Understand the problem from the start. Different issues require different approaches depending on the cause of the issue. For example, misfires from a single-cylinder setup are often caused by engine failures. Meanwhile, random multiple cylinder misfires happen because of outside sources rather than because the engine is malfunctioning. Finally, you won't get a misfire code for mechanical failure and unbalanced rotating assembly.
- Single-Cylinder Misfires: If you have ignition failures or fuel injector problems then this is usually the result. To make sure this is the case, check your plug wires, spark plugs, and ignition coil. If the coil is damaged it's quite easy to know and repair. However, many engines only use one coil to power its two cylinders. Therefore, it that single coil has issues it's likely that both cylinders will die out as a result.
- Random Multiple Misfires: You could suffer from this major cause of excessive car engine vibration due to problems with engine support systems like your electronics system, fuel supply system, or air intake system. A vacuum that's leaking air, a sensor that's failing, or an airflow sensor that's dirty can serve as potential culprits. Naturally, air intake restrictions can cause automobile vibrations too as a symptom.
- Mechanical Failures: Your car's engine might also shake excessively due to mechanical failures or problems. Namely, you could have issues with your camshaft, broken piston ring, or damaged head gasket that could lead to cylinder misfires and a trembling motor. If there are no misfires at all, the engine shaking can be caused by an unbalanced rotating assembly instead. Most engines use a harmonic balancer or balance shafts to reduce vibration. If you have one of those, have them checked. If they're damaged they might be the reason for the increased shaking.
