I have seen this problem a lot lately on the 99-03 3.8's with a lot of miles on the clock. Worn valve springs are the cause and usually a complete valve job along with new springs fix the problem.

But you may want to take it in for diagnostics to make sure there isnt a problem with the timing control.
