This was the first time I had started the car in over 1 week. When I started the car it idle okay for the first 2-4 seconds, then the revs started to bounce between 1800 rpms then drop quickly to 500 rpms. This caused the car to turn off. I started the car again and it started idling badly again. Then I started it again and I gave it a few revs to keep it alive and that worked and did not turn off.
