Default Need Help Cold Start!!

OK guys here is one for you. My C4 now takes a few turns of the key to get it started. Once it is running it smooth and drives fine. Now Say I drive it to work. When I come out at lunch or at 5 and it has set for a few hours it runs REAL ruff. If you turn it off and start it a few more times it smooths back out. Once you start it run fine. If you turn it off and restart after 10 mins or so it starts right up, It only when it sets for a few hours. Got any clues were to fine the problem. Thanks for any help

Is there any codes? Have you checked fuel pressure? Have you ohmed your injectors hot and cold? Trying to get a better idea of where to start.

do a fuel pressure test first, probably leaky injector(s) as the cars sits the injector(s) if leaking is just dumping fuel into a cylinder(s)
and giving you a flooded condition...at least that's where I'd start.

Thanks for the input guys I think that is heading in the right direction Has a pretty good gas smell when it does it. I was thinking about a bad injector
