Lack of performance in my C36 AMG

[big_turban]

Hi everyone,
I have a problem with my C36.
I was pulling out of a roundabout and hit the accelerator and nothing happened!
My car suffered a major lack of acceleration. The garage replaced the sparkplugs
and the coil pack (improved performance by about 70%) but the problem still remains. It has jerky, hesitant,
unsmooth acceleration. At 50 mph in top gear it rumbles when you put your foot
down. Anybody got a clue what's up with my car. Diagnostics aren't showing
anything up!
:cry:

Hi

Sounds like typical air mass metre (Maff sensor) this will not give a fault code unless it fails totally, ask the dealer to fit one to try, note they must reset self adaptation an engine, you should know imediatley
