hmm, odd. My f22 sounds the same way on colder days....
sounds like someone going PPBPBFPBTPBPBFPBPFPBTPFBTPBFPBTBPTFPBTBBTPFT with their lips
I just had my timing/a/c/power steering/water pump/seals all done, and it's less than it was... but sounds similar. I thought it was normal.
How about a nice mp3 of a slow rev to redline and back down? :thumbup:
