CLK 430 M113 bad acceleration, sluggish, limp mode

Hello so I have this problem since a few weeks that the car doesn't accelerate that well, thought it could be a bad MAF sensor or coils or spark plugs, I changed all of them up, and the o2 sensors which regulate the fuel mixture, but nothing. Still the same problem.
I have no bad air intakes, everything is sealed. The way I would describe the acceleration would be lower RPM it has good torque but until you give it throttle it just feels very slow and heavy on the acceleration, yet it still maxes out RPM, no problems. No sudden stops mid range or at the end.
The previous owner changed the acceleration sensor in the hood, the one with the hook attached to it.
Fuel pump and filter were also switched a couple months ago. Also, the car runs on LPG aswell, but the symptoms occur on both fuel types. on LPG it is a bit slower (when everything works) and on normal petrol, it runs fast.

What else can I be looking for?

how many mi? wouldnt hurt to run fuel cleaner through your system. i'd actually highly recommend it given your circumstances. Techron is probably best.

edit: and you have it on S, not winter mode? I feel these Mercedes are pretty sluggish at times unless you are hard on it, sometimes.. but I don't have any errors AFAIK

I had similar issues on my 2003 CLK 430, and have replace most of the same parts. Did you replace the crankshaft and camshaft sensors? Both are inexpensive and easy to replace in about 30 minutes.

Check the codes, but it could be a bad throttle position sensor.

To check the TPS try starting the car and open the hood, then operate the throttle position sensor by hand (left side wheel well). Mine was also bad and it was definitely slow to respond - RPM should follow the sensor position closely. Inexpensive 15 minute fix.
