[QUOTE="firasjawad, post: 913960, member: 19126"] I Usually get spark knocking at around 1600 rpm when I am cruising and the car shifts to 5th and you increase your acceleration slowly that it does not downshift. Please see the video i have i have recorded the rattle sound. I had the car since 2010 and installed the Whipple at around 2013. the car was great and no trouble in the states, but when i moved back to Saudi and brought the car i had this rattle sound increase by time. At first i thought it was a mad muffler i changed it but no luck. Ford Dealership told me to change the vct solenoid, replace Mass flow sensor, and put new spark plugs, but still no luck. I then changed the coils and spark plug wires and as you can see in the video still there. I was talking to a garage regarding the knock and he said maybe the fuel quality so he recommended to mix the gas from the station with 103 octane that reduced the knocking but still there. i am coming to think something is wrong with the fuel pump or internally in the engine. have any of you had this problem? your suggestions are appreciated [YT]DGX3Do6GRSk[/YT] [/QUOTE]
