Mitsubishi FGC25K 0R FG25K:
Part throttle engine stumbles

I'm working on a Fg25k , ser # af17c00583. The problem I'm having is at about three quarters throttle the engine is stumbling as if you've let off the gas, then when you go past that point it picks up just fine. And it doesn't do it every time, but it's annoying to the customer. I have changed the throttle body and mixer , still have the problem. Any help would be appreciated.
