hey fellas i just had one quick question ive pretty much changed all of these:

Belt Tensioner Replaced OEM Mercedes
Belt Replaced OEM Mercedes
Idle Pulley Replaced OEM Mercedes
MAF sensor Replaced (Mass Air Flow Sensor) OEM
Transmission Flush Done all Filters replaced Electronic connector replaced
Torque Converter Drainer and Replaced with new fluid
Water Pump Replaced BOSCH OEM
Power Steering Rack Replaced low miles part !
Air Filters Been Changed Kleeman OEM
O2 Sensors OEM

the only thing left now is TPS sensor i was wondering if it would fix my acceleration problem well here it goes:

Everytime when i drive not pressing the pedal real hard it would accelerate without a problem as soon as i try to floor it its like it dosent know what to do i have to play with the pedal and then the rpms jump up to about 4-5k rpms and the car starts to pull really hard how its suppose to i was wondering if this problem has to do with the TPS sensor in any way because i never got any codes maybe because its not completely broke yet sometimes it works and most of the time it just dosent know what to do when i floor the car !

i would appreciate any insight on the issue thank you guys again !

Have you change out the Fuel filter? you could have picked up bad gas, you could try some BG44K Fuel Cleaner from MB. Possible you have a vac Leak as well. This may not be a fix but I hop it helps

I was having accelerations issues on my 02 , I just had my throttle body cleaned , now she's pulling like a proper AMG ,

Try disconnecting the battery for a few minutes..

I have a TPS for sale brand new if you want it.

I would try a bottle of fuel cleaner and dryer, that's what I use when I have my car sitting in the garage for a few months in the winter time. When I accelerate hard, the check engine light comes on. After pouring a bottle of STP fuel cleaner and dryer to the gas tank, and a few hard runs on the highway, the light goes away and the car accelerate fine. You can pick up any brand, I use STP from Walmart and it does the trick.
