03 f4i unstable idle

Check your vacuum hoses. They may be old and cracked or one could have detached. I know (from experience) that the vac hose going to the MAP sensor can cause a wonky idle (usually high but sometimes low during warm up) if it cracks. My bike has a vac hose layout printed on top of the airbox
