I have had my car at the dealership 2 times for the following problem and I wonder if anyone else is having this issue. When the car is at idle about every 5-6 seconds I hear a bzzzzzz come from the engine compartment. It sounds as if the Vortech is making a vibration sound possibly harmonic in nature. The dealership believes it is due to the length of the support member that the SC is attached to. They have confirmed all the bolts etc are tight. Is anyone else having this issue?

 

I think I get the same thing as you . I think mine is intercooler pipe touching some where and vibrating .

 

booger - I notice that when mine occurs my A/F meter spike up slightly, are you seeing this as well?

 

NOOOOOOOOOOOOO......How much of a spike you talking about ?

 

My Wideband gauge displays around 14.5 ‘ ish at idle and when the sound occurs it goes to about 15.5 then back down. Where does yours sit at idle?

 

It goes from 14.7 to 15.2 . Well come to think about it . After I installed the crawford cats . It really doesnt jump around much at all any more. It stays right on 14.9 most of the time at idle

 

Well I feel better then, I thought mine was high but I guess not. Thanks


PS. I spoke to Vortech today and they said the vibration is the Jackshaft and that it just happens. I am going to get Grubbs to call and order a replacement and see if the original problem goes away.

 

Are you talking the whole jackshaft assembly ? If so how much $
