Weed wacker exp

[Exp05_intake]

Before i waste 150$ to get it checked at a ford shop im going to give it a last try here what can make my 05 ford exp EB sound like a weed wacker its driving me crazy lol

 

[GAINMOB]

what are u doing when u hear this sound...upon start up? driving? stopped at light? acceleration? explain...

 

[Stoned06]

Exhaust leaks at the headers can make it sound "sputtery", but a little more info to diagnose the sound might help.

 

[Spooky]

Broken radiator fan blade?

The sound is apon acceleration the mufler shop said it was the glass pack i have that makes that wistle like sound

Is it installed backwards? I have heard of glasspacks making weird noises if the packing is not facing the direction of exhaust flow.

Never thought of that but just to make sure im installing a magnaflow today ill let u guys know how its gose an one more thing do u guys know if a bad throttle body causes the rpms to stay real low when its in parking like 400 to 600 rpm
