Engine Hsistation

Sounds like classic example of arcing spark plug wire(s). I'd be willing to bet you need new wires. If that's the case, you'll probably want to replace plugs too, as your'll have access to them at that point.

Thanks for the advice on the wires and plugs. I'll give that a try. They are probably due to be done anyway.

It seems a little early, with the low miles and model year, but a possibility nonetheless. It's an easy do-it-yourselfer, but a shop will charge you a bunch. Stay OEM with the plugs and wires for best results. They aren't cheap - plugs are about $5.50 each and the wires will probably be around $100 or more...can't remember what I spent. Big difference though, and my fuel economy went up about 1.5 mpg on long highway trips.

I'd check your diagnostic codes to see if the car is trying to tell you something before doing anything. The plugs and wires should last to about 100K, but sometimes things fail early and in this case it only takes one bad wire to ruin the way the engine runs.
