I've checked them with a plug tester and everything is fine. I was thinking, could the coil be weak or is it the timing

Spark plug misfiring
What engine do you have 3.9 or 3.5? You may have gotten a bad spark plug. Pull one wire off at a time to see if there is any change in the way the engine idles. If you pull the wire off the plug that is bad there will be no change in the way the engine runs.

timing does not change from changing your plugs. I asked what type of plugs to see if they were cheepos. like cdminter59 says check the plugs. Also are you sure you have the wires correct and on tight.

What brand plugs. If they are Bosch, throw them away and get some AC's.
Was it misfiring before you changes them?
