My check engine light comes on goes off, currently on. It has 146k miles. Last year I replaced one of the sensors related to the vacuum in the tank. I was told to stop topping it off. It was off for 6 months or so, but now intermitant. Any ideas?
Yes , have the codes read at Auto Zone or any parts store that will do it for free and you will get more suggestions . Post the actual code , not what you or the clerk think it might be.
