I am hearing a very annoying noise coming from the middle or rear of the car ... For example if I am waiting a red light and I want to go full capacity I hear the noise something like a " PAA " then everything returns to normal... it is something like a hesitation before acceleration
The engine light is OFF and there is no alarm light On ! what do u think it can be the wiring harness ... My car is C280 1995

NB: I feel that everytime the noise come from a place in the middle or rear sometime from the middle front.

Please HELP!!!
