I noticed that I had no engine oil this morning, after noticing the car idling rough the night before. I filled the car up with oil, but it is still idling very rough. The car has had a recent tune up, and the check engine light is not on. The car runs smoothly when driven at high or low speeds , but when parked or stopped at a light, it runs and shakes roughly. Help?

i had the same trouble, there is a rubber boot under the cover on the top of the motor, it is coming from the egr valve, takes about 5 mins to repair and less than 5 dollars.
SOURCE: Very rough idle and low rpm and flashing service engine light.
Don't think it's major could be any number of sensors. Any autozone will run a free scan and point you in the right direction.
Testimonial: "Ill let you know."
SOURCE: 1998 ford ranger idles rough, high then low
does car have engine codes? sounds like your idle air controle valve is sticking. or possible egr problem
SOURCE: car idles rough in park also runs rough in overdrive
Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.
