I see a lot of new cars with ignition coil failure. They are relatively easy to replace. Look at www.rockauto.com for the parts price go with a good "known" brand labor to replace depends on which coil has failed. When were the spark plugs last replaced a bad plug puts pressure on the ignition coils to supply a greater spark. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
