My 2010 FL2 has started losing power randomly while driving. The engine idle's fine just drops and recovers when I change gear.
Can anyone point to some possible root causes ?

thanks in advance

How much fuel in the tank? If over four gallons, check the internal fuel tank pump is lifting fuel over the bump in the tank. If it appears to work, Change the fuel filter. then see what happens. Sometimes the under body wiring loom frays over the centre of the prop shaft or exhaust. Until you have done the basic checks, you will spend money unnecessarily. Next possibility is the high pressure pump, or camshaft end that drives the pump, see what I mean about cost.

Ive about 1 gallon in the tank

Put more fuel in the tank, preferably ½ a tank and see if it still does it.

Question, does this only happen when changing gear? Does it feel like the turbo is loosing boost momentarily? Hyundai Ioniq 5 Ultimate. The replacement for the SE.
2009 Rimini Red SE TD4. Almost sold.
2006 Tonga Green i6 HSE. Gone.
