Lights on
 

I have a 07 equinox. We just traveled from SC to illinois and in kentucky my service engine light,stability control amd traction control lights came on. I took it to autozone and they said the code read it as my EGR valve was faulty.we leave for texas tomorrow morning and my question is,can I drive it that distance without something happening to it? Like stalling or breaking down on the way down. Will it be ok until I can have someone look at it this week?? Thank you
