Car starting

Hi,

In the mornings, my 2000 toyota camry hesitates starting up. Its not a significant problem at all (yet at least). Usually it hesitates the first time and starts by the second time. Occasionally (1 out of 7 times or so) it will start but then immediately stop. Then upon a second try it will start, albeit still hesitantly.

So far this is only a problem in the morning when I first start it. I live in LA, so its never really that cold. (However I leave for work early and its usually 45-50 degrees outside - cold for LA standards) Also, My car is parked outside on the street and usually slanted to the right or left towards the curb depending on where I find a spot -- so maybe that has something to do with it?

Regardless, this just started happening and I'm hoping that all it needs is a fuel-injector cleaner. All other times, it starts no problem.

Thanks much!
