Not the same, but similar issues on my V6 (see more from BUZZ for my history).
We just resolved the check engine light by learning that the engine control module was spiking voltage to the O2 sensor, frying the O2 sensor (problem was originally diagnosed as a bad O2 sensor, but we painfully, quickly learned engine control module was cause). Mileage is now improved from 23 mpg to 28 at least. IF dealer is willing, get them to find an engine control module for your V6 off a used car in the lot and try it out on your car. This diagnostic was a tough one for them to make and took quite a bit of time.
Previous to this last issue, random, tough starts were fixed by replacing air mass sensor.
Otherwise, plug wires and coil pack have been replaced in my car way back when engine stumbled at speeds and bucked.
Lots of issues over time for me, but I remain somewhat under the impression that I enjoy the car. At present, it's running tremendous. What else could go wrong? (I've done all the AC, strut mounts, shift linkage upgrade, new radiator, valve cover gaskets, oil pan, oil sensor, and timing belt changes).
