Last night noticed that in park or while idling, rpms were fluctuationg wildly, engine revving up and down.
Is this serious or can I drive it for a while before checking it out?
No warning lights are coming on.

Things you'll want to check are, The idle air control, it's on the side of the throttle body, the EGR for sticking open, And a possible vacuum leak. Get a can of spray gumout, start the car and spray around, pay attention to vacuum lines and manifold, if the idle changes, you found a leak. Poor mileage and these symtoms, I suspect a vacuum leak and or the need for a tune up!
