ok so resently i have noticed a hollow whistling sound under the hood whene excelerating , i dont think its affecting the performance ( atleast i cant tell if it is ). just cant figure out what bit is ,,,,,,,,any ideas ?

 

Its got a turbo??? haha

 

Whistling is most always a vacuum, air intake or manifold leak.

 

When was the last time you cleaned the throttle body, if ever?

Probably a vacuum leak somewhere though.

Does it do it while idling at all?

 

no i have never cleaned the throtle body ( doing it tomorow ) no whistling while it idels just whene accelerating thrue fist and second gear that i can tell

 

Pick up a new throttle body gasket when you clean it. I'm going to guess you have a vacuum leak somewhere.

 

Are the neighbors missing their cat?

 

did you change the air filter recently?

 

Been here, done this. If it is a whistle that sometimes pops up at idle as well as when accelerating and comes and goes, as well as sounds essentially like a whistle/whine, check your waterpump.

Like I said, be there, done that.

 

Mine whistles too.......happy Jeep if you ask me
