Could this problem also include shuddering/stalling when starting to accelerate from a stop? I get a slight shudder sometimes when stopping quickly, but its more noticeable at times when starting.

I had this issue and getting a new battery resolved it.

I just had the same experience for about 3 weeks of ownership. It never do that in this past 3 weeks. Tonight, i went out to get gas. Everything is find until i was on my way home, and coming to a roundabout, i brake and slow down the car, downshift to 2nd, and then the car stalled. NO CEL. I was stopped in the middle of the road. I tried to restart the car, it was difficult to start. It cranked, but did not start.
I tried to restart twice, and it didn't work. After 30 seconds, i tried again, and it started right up. i couldn't seem to find anything wrong with the car, i didn't feel the engine is bogging or bad idles, etc.

This happened again when i am approaching my driveway, downshift to 2nd, and speed is quite slow as i am getting ready to get on my driveway ramp. It stalled. And again, i had difficulty to start the car immediately. I have to give it a decent 30 sec to a min, it started right back up.... Still no CEL....

what's the problem here? i don't wanna get strand in the middle of the road again. It was quite dangerous.

I got into this situation here also where it stalled out and took a bit longer to crank over in traffic on a highway.

I have replaced the MAP sensor and the IAC motor with OEM units and its still acting the same. I've cleaned out the TB but I have a feeling it may be a sticky butterfly that could be causing this.

I would check the engine ground cable on the back of the head, this seems to cause different issues and replacing it has helped many owners.

There is a recent thread describing this. Good luck.

thanks Hfreak, i just took the car out and i noticed the car had stalled even when it was dropping back to idle at 5-600 rpms.
