Starting Problem?

[khiz]

Hi guys, I am just having a problem with my 92 240 when i start it. It starts fine in the morning but its when i drive it and the engine is warmed up. When i go to start the car when it's already warm it starts and the rpm shoots up like normal and it just comes right back down wanting to shut off. So i have to give it a rev and its fine.

This problem started after i had left my lights on all day and had to get a boost to start it. It was fine before that. I know its not compression because it idles perfectly fine when driving, its just does that when i start the car. any help would be greatly appreciated.

Thanks
