Intermittently Loses All Power While Driving ['09 Pontiac Wave]

[PalouseAveo]

The coil pack is very easy to replace. It may be difficult if some of the boots are stuck on the plugs though.

I have a 2009 Aveo that I purchased new. Shortly after purchasing the car new (1-3 months), it had a similar problem to yours. The car would lose all power and shut down while driving. I would have to coast to the shoulder, wait a few minutes, then it would work fine. It happened a handful of times, then didn't happen again for years.

Last winter, I was driving slowly on a gravel road and lost almost all power, when I pulled the vehicle to the side of the road it was idling extremely hard and the car was shaking. The check engine light also came on. After shutting the engine off, waiting a few minutes, and restarting - the car worked fine. I had the code scanned and it indicated a Throttle Position Sensor problem. However, after a day or so the error cleared itself and I haven't had the problem since.

Not sure if any of this helps you, but at least you aren't the only one this has happened to.
