Yes, that's really bad actually. Please consider the following: any car over 150,000 miles in my opinion, is not buy-able. In my personal experience, cars (top of the line and also cheap) rapidly deteriorate after 150,000 miles unless of course the engine is new/rebuilt.

The spark plugs on a 1999 Mercury Cougar are located under the cover of the engine. The spark plugs should be changed approximately every 60,000 miles.
