Hi everyone, so I have a 2000 jeep grand cherokee 4.0 with about 250k miles. This seems to happen whenever it's really cold or around freezing mark (32F). Whenever I try to start my jeep, it won't idle unless I give it some gas to keep the revs up otherwise the engine dies. Once I start it and give it gas for a few minutes it seems fine and will idle on its own. This has been happening for a while now, but like I said only happens when the engine and temperature are cold. Any thoughts on why this is happening or how to fix it will be greatly appreciated, thanks!
