Has your wiring harness been replaced? How are your spark plugs and coils?
How about your air filter?Are your catalytic convertores stopped up.?
In mph the engine has a governor to stop at 130 mph.

there are special look like racing mufflers catalytic convertors,they are rare to stop up.If you have a U.S.A. car,it won't run over 130 mph.

Thank you again... if this found in my car how i can delete it or ignore...??

thanks for all your ideas

it depends on where you live,a Europeon Mercedes should have no govenor.I removed my catalytics.But if I was to move to california I would buy Mustang Catalytics to replace the Mercedes ones.Why because their cheaper.
Also I forgot maybe the mass sensor or Maf needs new one.
