If your Check Engine light is flashing, you should pull over and call for a tow -- driving could endanger your engine and catalytic converter. If your Check Engine light was flashing but is now solid, you should still have your vehicle serviced immediately. If your Check Engine light is steady, have a mechanic examine the vehicle as soon as possible; there are many reasons the light may be on. If your Check Engine light is still solid after your service appointment, it’s OK to wait a few days to see if it turns off. If not, contact your local Midas to make sure your vehicle’s issue was resolved. One possible quick fix: Check for a loose fuel cap. If the Check Engine light turns off after tightening the cap, you’re ready to roll.
