Could be anything, you need to hook it up to a code checker to find out why the CEL came on. Vibration is always a bad thing for an engine, but with the info here it could be anything from ignition or fuelling issues to serious mechanical problems.

Check engine lights flash because there is a misfire. A misfire will quickly destroy your catalytic converter costing a lot of money to replace.
