The spark plug tubes need replaced.
Possible bad valve seals. I have had this problem with my 1999 and that is what I was told.
On a 1999 Chrysler LHS, the spark plugs are located under the ignition coil pack, which is situated on top of the engine. To access the spark plugs, you will need to remove the ignition coil pack by unscrewing the bolts or clips holding it in place. Once the ignition coil pack is removed, you will see the spark plugs in the engine cylinder head. Be sure to use the correct size spark plug socket and extension to safely remove and replace the spark plugs.
You need a spark plug socket with a rubber grip inside to lift the plug out.

Using a torx head wrench, remove the two screws holding each individual coil to the top of the motor. Once removed, the coil comes straight up and off revealing the spark plug below. The engine has no spark plug wires (a good thing if you ask me). Removing the spark plugs are extremely easy to do!
