I have an 16 year old Opel Corsa D 1.2 80HP ECOTEC and i stopped at a traffic light and after i went in neutral my car couldnt idle and the motor died. It actually stuttered for half a second around 500-600 rpm and then shut off. After that i power it up and imediattely goes under 600 rpm and dies while trying to idle. I couldnt make it idle for more than 5-6 seconds. I get the usual stalling lights - battery and oil red lights
What i tried and tested:
Tried to keep it revved at around 2000 rpm for 1-2 minutes but after i get my foot off the gas it goes slowly to 500-600 rpm then dies
Checked my oil level and battery voltage, which are fine
Made sure i refilled with petrol not diesel
Any ideas?
