Weird Flutter Noise

[dineth]

Hey guys,

I just got my water pump and timming belt and fan belt replaced, and everything seems fine and much smoother then before, how ever when i slightly rev the car and let go of the thorttle, the car makes a weird flutter like sound. I do have a k&N Pod filter and its pretty loud, but this sound is nothing i've heard before. and the thing is i cant see how the sound would be linked with any of the repalcement parts. Its ahrd to tell if the sound comes from the Pod (cos its pretty distinctive) or the engine. If its the pod, im fine but if its from the engine i might be a bit worried. I wonder if anyone have a idea what it maybe? I appreciate that it is next to impossible to guess for you guys without actually hearing it.

cheers,

Din.

Do you have an aftermarket blow off valve? If so, adjust the spring tention and make it a little more loose. Let us know if it still does it.

im pretty sure the engine wont idle with any vacumme hoses disconnected... it will stall... if all hoses are connected, try removing the BOV and make sure the spring isnt jammed or corroded...

good luck

If a vacuum hose is disconnected, the car will bring the revs up to around 2000 - 3000RPM.

I just tried it on mine... i disconnected the BOV vac hose and it stalled..

If this happened straight after they worked on your car it will most likely be directly linked to the work they carried out. The chances of it being something unrelated are slim to none. Take it back to them and tell them to check it over.

I am curious....did they also change your bearings?
