Idle Rpm Higher Than Usual at Matthew Greig blog

Idle Rpm Higher Than Usual. If the pcm offers no hints, the best place to begin looking for problems is with the idle air control valve/bypass air control (iacv/bac). The first thing to check is if the check engine light is on and what codes it is throwing. When a car idles rough but drives smooth, it is usually caused by a problem with the ignition system, the fuel injection system, or a vacuum leak. Ignition timing is too advanced. You can try cleaning it and see if that improves your idle speed. But if the engine is revving up while idling, even after it’s sufficiently warmed up, you. Adjusting the ignition timing too advanced will increase idle speed, and if the timing is too retarded, it will drop the idle rpm. If your engine’s idle rpm is higher than normal, it can be a sign of several issues. Some of the most common causes of high idle. Older engines may go up to 1200 rpm or more while warming up. Power, there are six common issues for high rpm. A throttle body cleaning is likely to cure the high idle speed as well.
