stopped up injectors?

Has anyone had injectors get so bad,they cannot go past 3500 rpms.I'm thinking my no full throttle issue could be injectors. I have perfect idle,its only when I stomp the pedal she acts like no fuel.

Could it be a clogged filter? If this is the S320, it could be tired plugs or wires.

New filter,coils,plugs,wires, and fuel pressure checked.Also perfect ilde no burnt valves.No vacuum leaks.thinking either stopped up injectors,or fuel pump volume.Problems started after I overdose fuel with Marvel Mystery Oil,has had 4 sets new plugs,and fuel tank was drained.

Based on Mercedes recomindation I double dosed with Chevron Techron injector cleaner.I can feel something happening already.I can hold pedal down,she will skip a few times then haul ass.Like something is getting unclogged

If your plugs are carbon fouled or black then you're running too rich.
The smell would indicate rich mixture due to high HC and CO levels.

Lean mix plugs would read white to blistering as lean mix creates heat and possible detonation.

If they are black then either fuel mix should be adjusted or ignition timing checked.

Have you checked your MAF?
If it is sending a signal to the ECU that it is not seeing enough air it will tend to limit RPM.

You also want to check the vehicle speed signal to the ECU.
It originates from the ABS or ABS/ASR control module.
Signal problem would limit RPM.
