does anyone know why whenever i run the engine the check fuel cap or presure light is on?? dealer told me that i had to run it but it's been a day and it's still on, i can go back to them and they'll start looking but i think i can do it myself

the light comes on if your gas cap isnt all the way on tight
is that what you are talking about?
