Title says it all... 04 fx4 engine will rev when I shift into reverse every so often. I *think* it does it more if I put it into reverse quickly after start up. Any thoughts or has anyone had this as well?

 

I kind of wondered why it does this, and then "slams" into gear? Anyone else have this happening to them?

 

Im guessing it "hits" reverse hard because of the high RPM, and having your foot on the brake? Im just putting that on the stoop and seeing if the cat licks it up though. Maybe a run up the flag pole to see if it flies would be better?
