If your Ford Contour is idling high that is a sign that your vehicle is suffering from a transmission issue. I suggest you find a high quality professional transmission mechanic to look at your Ford Contour. I also would get a second or a third opinion before I let any mechanic work on you car.

you have to concentrate and look upon the EGR valve. Sometimes the passage of the valve is blocked. you need to clean it first. You can take help a tool called hand vacuum pump to check the passage of the valve. If it is open then close it tightly and block the mouth with a good seal.

The simplest and cheapest solution would be to replace the air filter and spark plugs. Most of the time that will fix the problem, if you are still having trouble take your car in for a tuneup.
