ok, this morning the car started first go. I took it for a 15 minute drive and it ran fine until I got back home, when left idling after driving it for that long it was very rough, but didn't seem to do it when I was stopped at lights etc earlier. I then turned the car off and tried to start it again, it cranks but won't start. When left to completely cool it will start again. So it seems after the car is warmed up it idles rough, and won't start. Any ideas on what my problem could be? Any help would be much appreciated!
