Fluttering noise on acceleration

[DanielG]

Hi -- the noise continues.

Question: Is there an SRS sensor in the differential (there is some sensor there -- I have seen it)? If so, could this be a cause of the fluttering noise in the car -- specifically, the SRS light in the car has been lit since I bought it -- if the SRS system is tied to the differential could a problem with the differential cause the SRS system light to come on; and working the other way, if it is a faulty sensor in the differential could it cause the differential to behave badly because the car thinks that a crash (or other) condition is existing?
