My car was idling fine before but now it starts up and if I don't give it gas than it stalls out. I have to keep feeding it some gas for 10-15 seconds before it starts settling down with the idle. It just started doing this and I dont know why. The spark plugs should be fine but what else could it be? Any advice would be greatly appreciated.
Thanks
