What Causes a Car to Make a 'Tut-Tut-Tut' Sound Before Starting?

[DelJuniper]

It may be due to faults in the throttle valve and spark plugs. Below is an introduction to car starting issues: 1. Throttle Valve Fault: If the throttle valve malfunctions, it can cause difficulty in starting and produce a 'tut-tut-tut' sound. Cleaning the throttle valve is recommended, as it generally requires cleaning and maintenance after a certain mileage. 2. Spark Plug Fault: Issues such as excessive spark plug gap, reaching the end of the usage cycle, or carbon buildup on the spark plugs can also lead to difficulty in starting and abnormal sounds. Timely replacement of the spark plugs is necessary. 3. Fuel Injector Fault: Problems like clogged fuel injectors leading to poor atomization or carbon buildup are also related. You can first try cleaning the fuel injectors; if that doesn't work, replacement is the only option.
