what does check engine means?

It doesn't let you know specifically what is going on, just that something needs servicing & checked out, You need to go to some one with a scan tool, to check for codes, which points a person in the right direction to the problem.

It means check your engine- oil, coolant, belts, plugs, filters, etc. you are supposed to do this occasionally
