Hi Guys, 2003 600 F4i, after warms up, the idle is jumping mostly down 50-100 rpm randomly and if I try to hold the throttle around 2000 RPM, it is very hard to keep it on that number. Jumping up and down more then 200 rpm. If I adjust the idle **** to 1300 it jumps like 50 down very randomly. But if I make it to 1100, it sound just fine, and doesnt jump. But if I try to make it to 2000 rpm with the idle ****, its jumping like 200 rpm up and down too.. 62k km-s on it.
There is a video about it:


Any ideas?
