Hello,
I am sure that 7,000 RPMs was a typo? Should it not read 700 RPMs?
If the engine stutters at low RPMs with high load you most likely have an issue with the high-tension ignition system, either ignition coils or spark plugs. See image 1 below
The engine is fitted with eight ignition coils, 1 for each cylinder

It would be good to have the engine control module checked with a diagnostic tool.
To check if there is a misfire counter on any of the eight cylinders and possible fault codes set. An easy way to test is to apply hand brake and foot brake, engage D and mash the accelerator down. Keep it there with brakes applied for a few seconds (max 5 seconds) and feel if the engine is stuttering, also with the scan tool connected and set to record misfire counters. This cam guides you as to which cylinder is affected.
