Is it necessary to clean the throttle body for CRV?

It is necessary to clean the fuel system and throttle body for CRV. Not cleaning them for a long time can cause a significant decrease in engine power, leading to excessive gear shift impact. Below are the related introductions: 1. Cleaning the throttle body: Remove carbon deposits and gum from the throttle body to ensure smooth operation, improve fuel economy, and make the engine run powerfully and stably, enhancing driving control; 2. Cleaning the fuel system: Remove deposits in the fuel system to restore normal fuel injection, eliminate idle instability, poor acceleration, hesitation, and knocking faults; 3. Benefits: Reduce fuel consumption, restore the air-fuel ratio, and lower exhaust emissions.
Cleaning the throttle body is something I believe should be done regularly, especially for urban SUVs like the CRV. Having driven a CRV for several years, I noticed that during stop-and-go city driving, severe carbon buildup in the throttle body would cause unstable idling and even stalling. After cleaning, the engine ran much smoother immediately. Carbon deposits form from residual exhaust gases and accumulate on the throttle valve opening, restricting airflow, which leads to increased fuel consumption and reduced power. Therefore, I recommend checking it every 20,000 to 30,000 kilometers, or when symptoms appear, such as difficulty starting, rough idling, or a sudden spike in fuel consumption. The cost of cleaning isn't high—you can buy specialized cleaner for just a few dozen yuan and do it yourself by removing the intake pipe and scrubbing the inside. If you're inexperienced, a professional shop will charge around a hundred yuan. This isn't a major maintenance task, but it can prevent bigger issues, extend engine life, and give you peace of mind while driving.
