Intake Rattle on a 2006 Mustang V6?

[slpstell]

Hey everyone Im having a bit of an issue this morning.. I got in the car and was stuck in the snow punched it and got out.. now all of the sudden when i accelerate i get a rattle/squirt noise really strange. but it doeant do it when i idle or light accel. i brought it over to a local mechanic by my job and the guy said something about plastic runners in the intake manifold might have broke off? i have not a clue but its bugging me to death!!! any suggestions???

Uh i've got no idea what the heck that guy is talking about. If you have a rattle you have to go through the laundry list of potential sources to sort it out. Now it only rattle when you get on the gas hard? And from the front i am assuming since he said the intake manifold right?

I've had all sorts of rattles, clunks and pops. you just need to take you time and shake things, drive differently and attempt to isolate the area that is making the noise.

i highly doubt anything broke in your intake but it does sorta sound like you are having issues with your cmcv plates the butterflys in your intake manifold might not be opening and closing correctly... car feel any different power wise?

yeah i have no clue what he was talking about either. but its driving me nuts.. car feels completely normal power wise just sounds like something is broken inside but no other problems very odd...

the noise is isolated to the intake you can hear the rattle coming from it and when you touch it can feel it. but noise does travel so i can assume its that

when something rattles i break out my socket wrench and start to tighten and make sure all of the nuts and bolts are snug. I got rid of my front end clunk by figuring out i had 1/4 turn left in the swaybar endlink. Now i just have to get rid of the pop lol. So just tighten and inspect everything. Its a free repair in any event

id say if you were more local just come by with it and id take a look for you but thats a little bit of a trip

You know this may sound strange but I had this happen to me and it was a piece of ice stuck ratteling around and it sound like something had broken off

just my 0.02c

hmmm interesting theory...i like it

[slpstell]

well i have narrowed it down.. i brought it to a friend of mine and he told me to change the belt tensioner pulley assemb. the idler pulley and they belt and the noise will be gone.. i you tubed and google the noise its its almost dead on hope this does the trick..

ah wish I saw this earlier, I would've gone over to hear it, I had to replace my tensioner on my f150, had a similar issue
