Coils, Spark Plugs, Carbon

What is your question?

My RX8 is stalling on me. I have it at the dealer and they said I need to replace coils, spark plugs and clean out the carbon. My engine was replaced a few years ago and has only 10K miles on it. The dealer is wanting to charge me $1,500.00. This seems excessive. Can anyone give me an idea of what this should cost and the best place to bring my car to in Ft. Worth, TX? Thanks!!!
