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!

Hi there mate, I know the pain when no one replies, I has similar experience. Anyways..........I also got 5 Cyclinder and as far as I can think try replacing the coolant sensor that is located at the bottom of the radiator, thats the sensor that senses the temperature and makes cold start valve cut in or cut out

Try this: Engine Problems and Diagnostics (

That's for the 20V engine, but there is probably something similar for yours. For our 20V 5-cyl engines, it seems to be a very common problem. It could possibly be a weak fuel pump too.
