k so, after your car is warmed up, or you've driven it for a while, and you're waiting outside for your friend to run into starbucks and get a mocha double latte **** thing. So you're bored, and you rev slowly to 2,500 RPM for no apparent reason, just admiring how smooth the 12yo engine in your SVX is. And you let the revs down slowly, then you hit 2,200 RPM, and there's this...weird vibration that exists nowhere else in the rev range (believe me, I checked). Like maybe a little shake, no noise generated or anything...like a wheel out of balance at 60 MPH ONLY...just that one area. Anyone else have this condition with their SVX and do you know what it is? Maybe an out of balance crank pulley???
