My G3 yak engine has started to stop running. Everything was working fine a few days ago and now the engine quits. and even have trouble keeping a throttle curve. All help will be greatly appreciated.

When does it quit? Is this an edited version of the Yak? What do you mean you're having trouble keeping a throttle curve?

Yes it's an edited Yak, It quites on an upline or sometimes it will just go to to idle then to full power then back to idle.
I'll set the throttle for 8 points, hit save, and it will not save, most of the time, and never saves if I try it another day.

Thanks, jaafit, it's getting me down.

jaafit, The plane I had trouble with engine going to idle was a edit of an edit. Iwent back to the first edit and an orginal and they are ok,, I still can't keep a throttle curve tho.
