F115

[JakeLMert]

I have a 2005 F115 maybe around 100 hrs.
At idle around 750 to 800 RPM's it will sputter and jump up to around 1000 RPMs and back down agian. I take it for a run, cruise around at 3500 to 4000 for a bit, runs great. At idle it will sputter and after about 5 to 10 minutes of *****ing at 1000 RPM's it will quickily jump up to about 1200 RPMS, just a really quick bump up and them back to 1000.
Other than these issues it runs great and doesnt skip a beat.
Any ideas?
Thanks

possible leaking injectors, sounds like they are dribbling instead of atomizing..

thanks, anyone else have any input?
I will send off the injectors for cleaning and to get checked over.
Thanks

What would be the main cause for sudden quick jumps in rpms spark plugs?
Thanks
