My car is having issues with acceleration. Like 50% it goes like a beast and 50% its slower then corolla. So i took it to the mechanic and he is me telling me its a pedal sensor with the parts number 2033001204. My question for you guys is do you know any legit websites with decent prices to get the sensor. I looked for couple of hours and with no success.
Anything will be greatly appreciated..

I like www.parts.com. Also, depending on your location, I can lend you one to see if it will solve the issues. Because there can be other causes with the same symptoms.

Sounds like a intercooler pump failing? Do a search...

Usually if the pedal sensor went off, it would be accompanied by a check engine light according to what you described.

Is the check engine light on?

I had this problem before and it turned out to be my Throttle body not my pedal sensor. Did he pull the codes? One of my codes said Pedal sensor, but then there were other hidden codes that my code reader doesn't see that pointed to the throttle body.

I had my throttle body rebuilt by BBA remanufacturing.

Good luck, I hope it's just your pedal sensor!

Oh and parts.com has worked fine for me in the past too.

Thanks for the replay guys!
I just had my car for the service b with very qualify mechanic with over 17 years of experience and he only does mercedes.
He pulled the codes and Air temp sensor and pedal throttle sensor came on. He replaced the air sensor and he told me to drive for a bit and see if i still have that problem. Because those two sensor are connected and if one is failing other will fail as well. I still have power problem and it bugs me alot plus i spent lots of money and would like to get somewhere cheaper.
Been having bad luck with cars lately

it's not luck...these cars need to be fixed a lot!

The car before this one was fx45 were i had to replace 4 wheel bearings in 3 month and
