  • Is it bad to have check engine light on for too long? Trouble code P1450: Unable to bleed up fuel tank vacuum?

I won't have any money to go get it fixed until Christmas, which I'm supposed to be spending in Chicago and I'm driving 6 hours. Is it safe to drive 6 hours straight and wait about a week to get this fixed?
