Alright, I'm calling in some forum wisdom here.

Received a call from the dealership this morning. Bryan from Franklin Chrysler, Dodge & Jeep told me that the car was not showing any codes. I reminded him that the O'Reilly I stopped at was showing a Low Voltage code, of which he took note of. Of course, because no codes are are showing, they're suggesting a guess & check method. They want to start with a tune up--specifically, spark plugs (which they want $700 to replace), transmission flush, etc. In this same round, they're wanting to go ahead and replace the throttle body, which is a $1300 part. Quite obviously, I'm not to keen on throwing around this kind of money, (a grand total of $2800) with no real guarantee that it will fix my problem. The car has never had a "tune up," so I'm thinking this may be a good place to start. But if a plug was causing a problem with a misfiring of a cylinder, would it be this intermittent?

I feel like I'm being bent over and need some advice. Please help!
