Did they check the spark plug wire resistance, or have you previously replaced them? Most of the 05 wires are about 3 ft. long and, when in good condition, should have ~12000-20000 ohms resistance, end to end. Maximum resistance should be no more than ~10000 ohms per foot. Give some consideration to Taylor Shorty wires, if you need to replace them. I've had them on my 05 Hemi LX for about 6-7 years now and, IMO, they're great.
