Does Throttle Body Cleaning Require Matching?
1 Answers
After cleaning the throttle body, matching is necessary. Failure to match can lead to the following consequences: Short-term increase in vehicle fuel consumption: If the throttle body is cleaned but the computer is not matched, the system will continue to use the control logic for a throttle body with carbon deposits to manage a clean throttle body. This will result in a short-term increase in fuel consumption. Over time, carbon deposits will form on the throttle body, affecting engine performance. Unstable idle speed: If the throttle body is not matched after cleaning, it usually results in a high idle speed, and in some cases, an unstable idle. An excessively high idle speed can also trigger the engine warning light, making normal driving impossible. The vehicle may accelerate rapidly without pressing the accelerator.
