The car always had some trouble startin when it was cold. I have to keep pressin the gas to keep it up, and or it'll die right after it starts. And I have to do this for about a minute until it'll hold it's own. But today when I started it, the car just ran like ****. The whole car was shakin pretty bad, and it sounded like one of the spark plugs wasn't firing, or firing outta turn. When I looked under the hood, I could smell gas and there was smoke coming outta the passenger side of the engine. I don't know what's goin on with it, any ideas??

Thx
