From what I have read they are most likely past due!

Mine is an 2004. I'm at 271000. Something I think about because of the mileage. Have not had any issues, but lets face it these things along with my heart will not last forever. You could try a injector cleaner. I had a rough idle at around 210000 miles. With a full tank I added some cleaner and within 10 miles, it ran perfect. Have not had any issues since.
Let's see what everyone has to say about new replacements when the time actually comes.
Good Luck to you timroberts..

I have used Stanadyne lubricity formula the last 310,000 miles when almost new on cold crank rough running and smoke. dealer flashed comp. twice no better started Stanadyne 1 month later smoke and rough idle went away.
