Rough Idle
Any of you guy's have any rough idle issues on a 97? I've changed my oil around 3,500 mi since new, grease joints @ 1500 mi intervals. The truck now has 271,000 mi on it and once you're rolling it runs great. Whether it's cold or warm weather it still idles rough. I haven't changed injectors yet. Any thoughts would be greatly appreciated.

I have a 97 that idles a little rough. It kind of shudders every 5 seconds or so. Power is also in question. I am waiting until I know it is not the fault or the winter blend fuel. There have been a lot of rough idle threads lately. Do a search and you will see them all. Are you using diesel kleen or the like?

Trucks with a manual tranny come from the factory with a dual mass flywheel and one indication when it's going bad is a rough idle.
