I hope someone can help. I have an 2006 LS with over 118,000 miles on it. On my way home this morning, my check engine light came on. My concern is since I cannot get it read until Thursday but need to drive it to work Wednesday, in general, would it be safe? I have a 110 mile drive to work so it would be 220 round trip. I have no loss of power, my display shows no errors, car seems to run fine except the check engine light came on. Would it be advisable to disconnect my battery, and see if the check engine light being on was just a one time thing.
