Misfire at idle?
 
Edit: Crap! Posted in the wrong forum. If a moderator would be so kind as to move to Technical, I'd appreciate it.

My bike has been occasionally misfiring a little at idle, as well as occasionally holding high RPMs (also at idle, but only after riding, never at startup).

Bike is fine cold, but then after 1-2 min:

Panigale Misfire? at Idle - YouTube

Been to two different Ducati dealers and so far nothing.....no codes are thrown, everything seems to be fine, only it's not.

Mine does that all the time, exact same sound. Got more prominent after the upmap this spring.

Just a little afterfire caused by the idle mixture being a tad rich. My Hypermotard did it all the time, no worry!

Bet ya it runs just fine with the throttle wide open;)

Yes, it does run fine WOT. Happy I'm not the only one. But with ride by wire and a pukka ECU the bike should know it's at idle....perhaps O2 sensor is mucked up? Sounds like shit and the bike does stall under partial throttle (and sometimes at idle). Not sure if any symptoms are being caused by the same thing. Bike is at MotoCorsa, and they've been pretty spectacular to work with so far. Stay tuned, should have more info tomorrow.

Have you ever changed the spark plugs?

FWIW, a BMW dealer told me that the ECU doesn't take input from O2 sensors when engine is cold, or at idle.

Kinds weird question...wtf is pukka?

Fragile Oct 8th 2013 10:23 PM

maybe an exhaust issue, broken weld or something. almost sounds like pressure builds and metal to metal slapping sound.

Very true!

Either that or you do what I did to "fix" the smoke issue: Only start your engine once you're seated and plop it in gear and ride off immediately. That idling business is not good anyways.:D
