Hi i Have a 3.5 liter 96 intrepid. Has 155xxx miles and recently stopped wanting to start in the cold weather like 10-30 degrees after sitting for more than a few hours. turns over and "coughs" like it wants to start but wont actually start unless i give it gas for about 2-3 minutes and shuts off if i take my foot off the gas before that. once it gets going it runs fine. i do know i have an issue with my EGR valve leaking because i can hear it and recently got a code that went away don't know if that could be a cause. Does anyone have any ideas as to what the problem could be??
