Narrative:

At 15 mi wnw, engine began running rough and was showing obvious mechanical problems. After the use of proper checklist, was unable to solve problems, I decided to glide into sheridan airport instead of buffalo (destination). I called on the proper frequency 8 mi out and obtained proper response from the fire fighter department at the sheridan airport. I was 2 mi out on base for runway 14. I made the proper calls, declaring an emergency. A beech 1900B asked if they had time to 'blast off' before I could get in. To which I answered 'I don't know I have a lot of altitude to lose.' (I was very busy.) they got on the runway, they saw that I was on short final with true problems. Then they decided to get off the runway. They were apologetic upon my clearing the runway. Hopefully, they will remember next time that per FARS that emergency landing traffic always has priority over anyone else -- even when it's a rushing commuter.
