Cooking, little fingers, and other activities can leave grease spots on your wallpaper. This is a guide about cleaning grease off wallpaper.
We recently bought a flat and the kitchen is papered in quite a thick embossed wallpaper. However, as it's in the kitchen it's smothered in quite a thick layer of grease from years worth of cooking.
If there's a walmart near you, try to pick up some Awesome cleaner. It's a yellow liquid and can be used for many things. The dilution is right on the bottle. Mix it up and scrub it clean. It will take off nicotine from walls and grease from surfaces. It has a nice scent too I think (clean)
If you can't find Awesome cleaner (I noticed you said flat. I suppose you are not in US) Try any degreaser. It will take of the grease. If you have Dawn dish soap, you can use that. Add a bit to some hot water and scrub the walls. Just look for a product that says degreaser.
To remove grease spots on wallpaper, hold several white paper towels over the spot and press with a lukewarm iron (hot may set the stain) until the grease is absorbed. If the paper is washable, follow by sponging the area with diluted dishwashing liquid. For non-washable paper, apply a paste spot remover; brush off after it dries to a powder.

I recently bought a mobile home and the people who lived there before me never cleaned the walls. I do not wish to paint over the kitchen, but do not know how to take off the grease without ruining the wallpaper. Any Ideas?

I have used Greased Lightning with success. I buy it at Wal-Mart but know it's available other places as well. Be sure to try it on an inconspicuous place first as it definitely takes paint off some surfaces, so it may damage your paper.
You might also try Murphy's Oil Soap. It works for cleaning the whole house. My parents had the same problem in their trailor behind the stove. It's tough to get out.
It may be way too late for the original questioner, but this may help others who come to this question. I have cleaned greasy wallpaper with cheap white bread. Just rub it with a piece of bread held like an eraser until it has soaked up the grease and dirt. Throw the slice away and start with a fresh piece as often as necessary. If there is a lot of grease, use pads of paper towels and a WARM iron to leach the grease from the paper first.
Maybe this is a dumb suggestion, but have you tried blotting it with a very slightly damp cloth? You don't want to rub at it, but you might be able to get a fair amount off just by soaking it up on to a cloth. Most wallpaper can survive a little water. I suppose you could also blot it with a cloth in rubbing alcohol, which will take the finish off things, but will leave colors untouched (usually). As always, try in a corner you're covering with something.
To remove greasy spots on wallpaper, apply a paste of cornstarch and water. Allow to dry. Then brush or vacuum gently.
For bare spaces in wallpaper; color in with felt tip marker. This works for small spaces or ones that are not visible.
