Does the Spirior have high idle speed after cleaning the throttle body?

[RubyDella]

Spirior's idle speed becomes higher after cleaning the throttle body. How often should the throttle body be cleaned: It is recommended to clean it every 20,000 kilometers or 24 months. The specific cleaning cycle should be determined based on personal driving habits and the driving environment. If the air pollution is severe or there is a lot of dust and poor road conditions, it may need to be cleaned every 10,000 to 15,000 kilometers. Or if you drive in the city for a long time, with congested roads and frequent stop-and-go driving, it may also need to be cleaned every 10,000 kilometers. Throttle body: The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. It connects to the air filter at the top and the engine block at the bottom, and is known as the throat of the car engine.

When I cleaned the throttle body on my Honda Spirior, it's indeed possible for the idle speed to increase afterward. This mainly happens because the carbon deposits on the throttle body are removed, making the air intake channel more open, but the car's computer still retains the previous memory values and doesn't adjust to the new state in time. Higher idle speed can cause unstable RPM, which doesn't affect driving in the short term but may lead to increased fuel consumption and potential engine damage over time. My solution to this issue was to let the computer relearn the idle speed. The specific steps are simple: drive about 20-30 kilometers to let the system adapt automatically, or disconnect the battery for a few minutes and then reconnect it. Don't rush to fix it—give it some time to adjust. Once the idle stabilizes, everything will be back to normal.

I've also encountered high idle speed after cleaning the throttle body, especially on models like the Honda Spirior. During cleaning, the removal of deposits alters the throttle position, and the ECU's settings can't immediately adapt to the new airflow, leading to elevated idle speeds. A simple solution is to reset the ECU by turning off the engine, disconnecting the negative battery terminal for a few minutes, and then reconnecting it. If the idle remains high, check for poor sensor or wiring harness connections. However, most vehicles will self-correct after a few weeks of driving. Don't ignore this issue, as prolonged abnormal idle can increase engine load. Just pay more attention during daily driving.

It's quite common for the idle speed to increase after cleaning the throttle body on the Spirior, and I've experienced it myself. The cleaning alters the airflow, and since the ECU hasn't updated its settings, the increased airflow causes unstable idle speed to rise. The key to solving this is to let the system relearn—either by driving a short distance or performing a power reset, both of which are effective.

Why does the idle speed increase after cleaning the throttle body on the Honda Spirior? I've dealt with similar issues, mainly due to the ECU memory not being reset, causing idle control malfunctions. The common method is idle learning: start the engine, let it idle without pressing the accelerator for a few minutes, and the ECU will automatically adjust. If that doesn't work, check the wiring or seek professional maintenance. High idle speed left unchecked can increase noise and fuel consumption.

After cleaning the Honda Spirior's throttle body, high idle speed is common as the ECU hasn't adapted to the post-cleaning changes. The issue stems from throttle position sensor calibration, causing persistently unstable high idle. Recommended solutions: let the system relearn by driving at cruising speed for several kilometers until RPM gradually normalizes, or disconnect the battery briefly before reconnecting. Address this promptly to prevent fuel consumption or engine longevity impacts. Always pay attention to reset procedures during routine maintenance.
