Which engine is it? The Hemi's have 2 per cylinder. My 2008 had regular plugs that needed to be replaced every 30k. It's not a difficult job to do yourself, look up youtube videos for step by step. You need a socket, extension, spark plug socket, a swivel joint, possibly another extension and a socket for to remove the coils. Buy a gap tool to check the gaps, but they are usually correct out of the box. $20 to $30 worth of tools and a few hours of your time can save a lot of money. Plugs are a good place to start with issues like you are having. Also if you have a hemi, change the PCV valve, I went for a year going to 2 dealers and my regular mechanic trying to fix a check engine light issue that was being caused by the PCV valve.
