I have a 2007 limited with 800 miles on it. It idles a bit rough, not terrible, but you can definitley feel some slight vibrations. Also, I noticed when standing outside the truck that the muffler (or something in the exhaust system) is noisy. Not really loud, but you can hear it puttering away (looked underneath and do not see anything dripping or smoking). Is all of this normal for a 2007 Liberty?

I should also add that a day after I got it they had to replace the Crankshaft Position Sensor since it was stalling on me. No stalls since.

when they are cold and not warmed up they idle a bit rough. And yea i think everyone has that noise you are talking about
