2002 Dodge Intrepid Ticking sound in engine

Last week I was driving in a terrible ice storm and after constant accelerating many pushes I was able to make it home. Although, after this trip my engine began making a ticking noise. A few days later, my oil light came on and I added oil. And, a few days after that when driving it began missing and sputtering and jerking while driving. I made it home and about an hour later it would not start. NOT sure what to do. Any thoughts?? Please advise.
Thanks.
