Is it normal for the Buick Excelle to idle at 1000 rpm?
2 Answers
An idle speed of 1000 rpm for the Buick Excelle is relatively high, as the normal idle speed should be below 700 to 800 rpm. Here is some relevant information: Idle Speed: Idle speed refers to the operating condition of a car when the engine is running in neutral gear. The engine speed during idle is called the idle speed. The idle speed can be adjusted by modifying the throttle opening size and other methods. Excelle: The Excelle XT and Excelle GT are the latest premium mid-size cars launched in 2010 by Shanghai General Motors Buick brand, based on a global platform with European and American technology. The Excelle is a premium mid-size car introduced by SAIC General Motors.
My Buick Excelle has been running for two years now. It's completely normal for the cold start idle speed to be around 1000 RPM when the engine is warming up, and it should drop to 700-800 RPM after a few minutes. However, if the idle speed remains at 1000 RPM even after the engine has warmed up, then there might be an issue. Possible causes include carbon buildup in the throttle body or a faulty sensor, which can lead to increased fuel consumption and reduced power. I encountered a similar issue last time, and after having the throttle body cleaned at a repair shop, it returned to normal. I recommend paying attention to your car's condition regularly—listen for any unusual engine sounds or use a simple method: observe the tachometer 10 minutes after starting. If the idle is unstable, get it checked early to avoid bigger problems and save on fuel costs. During regular maintenance, have the air filter and sensors inspected to ensure smooth and worry-free driving.
