The problem symptom I had was that the car would hesitate and not shift into 3rd gear at the right time. It would just rev up and wouldn't shift until I let up on the gas and then accelerated again.

Hay guys, Before one week while driving I heard sound then I stopped and found the fan belt cut, I have changed it with the wheels there. After taking the car from the shop the light Engine goes ON, after checking with the computer (OBD II) the fault was found on the 2 knock sensors. Now while driving I feel the power of the car is less than before and the shop guy said I need to replace the 2 sensor (which locate inside the Engine) :tsktsk: Is this sound normal?? should I believe him again?? it will cost me around 400$ with the parts
