What causes the Elantra to shake at idle?

The reasons for the Elantra shaking at idle are: 1. Dirty throttle body; 2. Faulty spark plugs; 3. Engine cylinder misfire; 4. Aging rubber components in the engine and transmission mounts. Taking the 2020 Elantra as an example, its body dimensions are: length 4510mm, width 1765mm, height 1470mm, wheelbase 2650mm, fuel tank capacity 50L, and trunk capacity 490L. The 2020 Elantra is equipped with a 1.6L naturally aspirated engine, with a maximum power of 90.2kW and a maximum torque of 150.7Nm, paired with a 6-speed automatic transmission.

My car has experienced idle shaking issues, which are usually related to engine system problems. Worn spark plugs, ignition misfires, and fuel injector carbon buildup causing incomplete fuel combustion can all make the engine shake severely at low RPMs. It's recommended to visit a professional shop as soon as possible to check the spark plug condition and clean the fuel injectors. Don't delay, as it may damage more components and affect driving safety. Additionally, regular oil changes and air filter replacements can prevent carbon buildup, which is crucial for extending engine life. Developing a habit of servicing every 5,000 kilometers can save a lot of trouble and expenses.
