We've discussed on here a million times the bucking and jerking that occurs when my AEM intake gets wet. Well, last night the usual happened. Intake got wet and the exhaust note sounded stuttered -- like the exhaust was combusted twice in a row or something when you punch it in 2nd or third. After that and some wheel-hop I started getting this weird buzzing noise every time I boosted, like when you get a peice of paper stuck in a vacuum cleaner. I opened the hood and it sounds like it's coming from the supercharger, but it's loudest when i put my ear at my driver's side front tire, but I can barely hear it when I put my ear over the intake in the engine bay. So I'm confused and scared.

I don't want to think that I messed something up internally, but I haven't had a chance to get the CAI off and dry it and check things out. so, what do you guys think it could be?

 

hmmm...maybe u have a vacuum leak or clog. i had a vacuum leak and the same stuff happened. it wud b jerky, and all messed up.

 

and what would a vacuum leak sound like? Would it make a buzzing noise? I hope it's that simple, that something just came lose maybe.

 

time to take the intake apart and have a look in there... shouldn't take long to do.

 

I just had this happen to me tonight... I was showing showing off to one of my buddies and the car wheel hopped a bit and now it sounds exactly as you say... like holding paper to a vacuum or in front of a fan... I am worried too, i checked everything and nothing seems loose. Mine also sounds like it is coming from the supercharger. I have no engine upgrades as of yet so i don't think you have to worry about it being your aftermarket intake. I believe that something is wrong internally. I am still under warranty so I am calling my dealing tomorrow to have this checked out right away. I also only hear it when accelerating. If you have found out anything further since you first hear it please let me know!!
