I dont know why but on my 2000 Mustang everytime I accelerate it sounds like there is a rattle coming from the engine. I took it to the mechanic but nothing has been found wrong with it. Anyone ever encounter this problem? I seriously need to figure out what the issue is because I am trying to sell my car.

 

something maybe wrong with ur throttle body and how much it opens

 

could that have happened from when i installed the intake?

 

its possible since you had to connect part of the intake to the TB.
make sure the CAi is securely in place.

 

is it a rattling or a ticking[&:]

 

hey, i had a similar problem. bring it back and have them check the transmission mount. maybe it needs to be replaced. good luck!
