My 2000 Jeep Cherokee Is Experiencing Rough Idle On Initial Start Up (Outside Temp Approx 18-19 Degrees). Once Warmed Up Runs As Normal Any Suggestions?

It could one or two things first it could be your fuel line partially freezing because you dont have enough gas in your tank or you have bought some bad gas that has some water in it. Second it could be your oil if you have not changed it lately I would suggest doing so. Also check what weight your current oil is it may be to heavy switch to something like a 5w-30 depending on what kind of car you have. Check your vehicles manual for manufactors specifications on oil weight. The problem is when it gets that cold the oil becomes like molasses until it heats up and thins out.
