I just thought I would share this one with you guys. Yesterday morning I was driving the '06 to work when at 60mph in 5th gear and 2/3 throttle the engine lost all power and the CEL came on. It did not stall, but instead would not rev or make power. A quick inspection under the hood showed nothing. I shut off the car and started it again, and now the RPMs were flopping from 2k to 200, back and forth every 2 seconds, and it still made no power. I shut the car off and looked under the hood again. Still saw nothing. Now the car had been sitting off for a minute or two, so I started it again. It started hard (cranked for 5-7 seconds and finally started when I pushed down the gas pedal a little) but this time it ran and made power. I started driving it again and since it seemed to be driving fine, even though the CEL was still on, I drove straight to the Dealership. They said it threw a P0607 Code which stands for Control Module Perfomance. The said that there was a Re-flash for my ECU that had been issued some time ago, but was never done to this car. So they did it and expect that's all it was, a known issue in the ECU programming that should be fixed by the re-flash.

 

The funny part of the story is that I had been having what I thought was some strange behavior from the DBW electronic throttle. Now, it's only been one day, but those things seem to be much better now.

The reving between 200 and 2k rpms sounds more like a vacume problem? Maybe something leaking.

Exactly what I thought, but I couldn't find anything, and there were no stored codes for it. I was also thinking it could have been the air intake tube partially off the back side of the MAF or throttle body allowing air in post MAF, but everything there was fine as well. I didn't touch anything and it started workign fine again after the 1-2 minute shut off.
