When my car hits about 1750-2300 it makes what sounds alot like an electronic beep?!? I have no idea what it is, maybe someone else has had the same prob? Never seen that b-4, but i plan on taking it to m&s see if they can fix it, because it also idles pretty rough, my other dsms had rough idle but this one is jumping like honda status. :? He said he had an safc in it and it got stolen, related maybe?
