Q: Check engine light on
I usually drive without much fuss, but the last two times I have stepped on the gas fully to quickly go by a slower car the check engine light has turned on. The first time it blinked and then turned off. The second time it stayed there. I understand I shouldn't leave this problem be for too long but my budget is tight and I won't be able to have it checked for at least another month. What could it be? Thanks.
