Hi guys..
Am having very weak / slow acceleration on my C43, i drive my car daily to work and never had any issues related to the engine or the gear, i parked it for 3 days without moving it and today morning i felt the problem.. (acceleration became as slow as the C280)..

Current mileage is 86000 KM, major service done at 75000 KM replacing Engine Spark Plugs, ATF, Gear Filter, Fuel Filter (all replaced with OEM parts).

Could it be an electronic fault?

Thank you guys in advance...

Bro.,

There are many issues about acc., it could be "CPS/TPS/MAF/fuel pump/fuel pump relay",

did you diagnose the car....??

did you try an STP injector cleaner in the gastank?
clogged injectors kills performance

try the easiest stuff first
how new are your eir filters?

Any codes showing, when you do a scan?

Please elaborate on what you mean.

Is the throttle response severely limited? Or is the car just not as fast and powerful as it should be?

Those are 2 totally different symptoms.

Hi to all..
I apologize regarding the delay from my side to answer your questions..
Currently am in possition where i cant use smart phones or labtop (working at offshore).. and unfortunately i will stay there until the next week!

ZAYED,
sup bro? i hadn't any free time to take my car to do check-up, but definitely i'll ask someone to do it instate..
CPS,TPS,MAF and the fuel pump relay this all could be the reson but the the fuel pump still new..

kowalski,
Am using STP injector cleaner oftenly every 10000 KM, i've used it once when i purchase it and i'll be using it again (I believe it gives positive results)
My Air Filtrs are brand new (K&N)

mercedes4ever,
I will do scanning as soon as i get free time..

Sulaco,
the car just not as fast and powerful as it should be, plus i've noted that there is cut-out when pushing full acceleration (almost half seconds)..
Before, when i turn the ESP mode off, the tires burnout at full acceleration, but not after this bloody issue happen.!


I'll be updating this thread when i get time to fix this problem (and hopefully with photos / videos), meanwhile your thoughts and your experience in this matters will be MOST appreciated..

Finally!! i diagnose the car and scanned it and find out the problem was in the MAF sensor, so replaced it with Bosch brand.
The MAF sensor will not be activate until the ECU is reset, so i reset it and let it re-learn! now i feel its even much better then what it was before..

Regards..
