What are the effects of a dirty throttle on the engine?
2 Answers
The throttle is a controllable valve used to regulate the air entering the engine. It is located between the air filter (upper part) and the engine block (lower part), and is one of the most critical components in the engine system. Symptoms of a dirty car throttle include: 1. Affects the precision and smoothness of engine air intake, causing the vehicle to shake at idle. 2. Impure air entering the engine combustion chamber, resulting in insufficient power during driving. 3. Increased fuel consumption. 4. In severe cases, it may cause the car to stall. 5. Abnormal engine operation, leading to difficulty in starting the vehicle.
Once while driving, I noticed the car was shaking badly at idle, and there was no power when I stepped on the accelerator. It turned out the throttle body was dirty. Carbon deposits had built up, blocking the air intake to the engine, causing insufficient air supply and unstable idle. At red lights, it felt like the engine was about to stall. Acceleration was sluggish, making overtaking difficult. Fuel consumption also increased because the engine had to burn more fuel to compensate, which hurt the wallet. Additionally, emissions worsened, with higher CO2 levels, which isn't great for the environment. Cleaning the throttle body usually restores normal operation, and it's recommended to check it every 20,000 km to prevent major repairs that could affect engine lifespan. Long-term neglect may lead to surface wear and accelerate engine aging. Pay attention to idle conditions while driving and address any abnormalities promptly.
