I just noticed today when I let off the gas in my sc4 there is a faint clicking noise and the petal slightly vibrates. It only does when I'm going under 40mph and its every so often not every time. I havent checked or done anything yet. I know that's not the greatest description but any info helps. Thanks!

 

Hmm, could be quite a few things, Your best bet is to first figure out where the sound is coming from (front left, rear right etc.) and once you've found out the source of the sound report back and then we can better help you out. If you're having trouble differentiating where the sound is coming from, have someone drive your car while you sit in the passenger seat or possibly have them drive past you, because it might be faint inside of the cabin but not outside if you get what I mean.

 

Have had that happen with broken exhaust supports right behind the front wheel area under the car.
