Default Cars StartUp is Different every day

Everytime I goto start my car the manner in which it starts changes. Sometimes it hiccups then starts, sometimes it fires up, sometimes in between the two. In addition sometimes it starts up smooth, and sometimes violently (rough/car shakes). Same thing with shutdown, sometimes its gentle, and sometimes it hesitantly shutsoff. Any ideas what would cause this? Leaks? Is it in the tune? Thanks

What kind of a tune is it? Open Loop, Closed Loop, SD, MAF?

Lots of things can cause some of the symptoms- would need to see the tune or have a lot more information. Could be anything from a Vac leak, something in the tune - a sticking throttle blade?
