Answer to your PM: The picture shows the part usually responsible, It's called the EVR. Sometimes you can take the top part off, and wash the sponge part in soap and water, dry it out and put it back together. In the picture it's upsidedown!
You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs!
