When I start the car for the first time after its been sitting overnight it starts and idles fine. When I shut it down and let it sit for a while then come back it starts then the idle drops and almost dies and bounces around then goes back to idling normal. Any ideas would be helpful . thank you
Have you checked for codes first?
It doesnt have any codes . the only one that comes on is for weak O2 sensor but thats after 10 mins of driving.
