LOL!!! I had the same problem. I can't recall the exact steps, but there aren't that many options, so you'll get this. With the car running, press the Info button on the left side. It will cycle through the various statuses of the car. At one point, it will get to the Oil and will tell you something like "Press Reset if New." Press it and hold that darned button until it acknowledges that you changed the oil. It will reset that message from 0% to 100%. It took me a couple of tries to get that to reset. Just keep trying it till it resets. You'll get it.

Go to a automotive store and tell them you have a 2005 Mercury Montego and what engine it has if there is more then one model and get an oil filter and the oil. Put the car up on ramps and secure it making sure it won't roll back or fall while you are under it. get under the engine and look for the oil pan which should have a bolt in the bottom of it where you can drain the oil. Drain the oil in a proper container and then put the drain plug back in the pan. Then find the oil filter and unscrew it and remove it.. It could be full of oil so watch out and make sure the pan is underneath the filter. Wipe the base where the oil filter screws on and make sure the gasket from the old filter is not still on the engine. Get your new filter and take your finger and put it in one of your new containers of new oil and spread that on the gasket of the new filter. Screw on the filter until the gasket touches the base and then turn only a little more then a 1/4 to 1/2 turn tops. Do not over tighten the filter. Find out what oil the vehicle needs (probably 5-30) and look for the oil cap on a valve cover under the hood. It probably takes 5 quarts but check for sure in your manual or ask when you are at the automotive store. Put the oil in and put the filler cap back on. Now go start the vehicle and make sure you have oil pressure by either the oil pressure guage showing pressure or the oil pressure idiot light goes off and while running check under the car for any signs of leaks. If no leaks then back the car off the ramps and shut the car off on a level surface. Let it sit 10 minutes and check for leaks underneath the car and check the oil dipstick to make sure the proper level of oil is in the engine. Then you are set.
Always check your air filter when changing oil to make sure it is clean as that helps your engine run better and you save gas in the process. Good luck
It is also best to change oil when your engine is warmed up as well.

Try a salvage yard for the part. As soon as your new car left the lot it became a used car. Used cars run on used parts.
If the old part is a recall they will upgrade you regardless which part is on your car.
Check the internet and enter your part# in the search box of the Browser. You may get lucky for a new part.

These codes relate to an electronic throttle body fault. Normally its from dirt, hardening oil deposits jamming the throttle body movement. Try cleaning the throttle body first before going down the replacement route. Hope this helps....

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
