Every time in the morning or after the car sits for a long period of time, from 8-12 hours or more, I have to try and start it over and over. It makes a nasty choking sound and usually takes four or five tries while I press the gas pedal to start.

If it sits less time it usually starts right away without any trouble.

I know it's not the starter or the battery because I just installed brand new one's less than two months ago.
