So the weekend doesn't get boring for sure!

Just happened on my way home two times and I could reproduce it

On my way to a roundabout, engine just running since half a mile, pressed accelerator once app. half way and then let lose again - engine stalled - (always nice in a roundabout with power steering and automatic transmission).
After app. 1 mile next roundabout, same procedure, same result.

Then on the street where I live let the Meggy just role, short accelerated, left lose, stalled. Shift in Neutral, restarted engine, shift in D -> running. Waited app. 100 yards, pressed short accelerator, left lose, stalled.

Then on the driveway I relized that the idling went up to 1500 rpm. I switched the engine off, started without pushing the accelerator -> engine short started but than died. Started again with slight pushing the accelerator engine kept running but again at 1500rpm.

I know of one "fault":
- My battery is on the verge to be dead, I will replace that one tomorrow.
There is no warning light on or flashing, nothing.
Before I start searching tomorrow in the middle of nowhere: Any suggestions what I should check first?
Thanks for your replies!
