That's because your plenum gasket is probably shot! Have you checked it?

 

no i havent checked it. It is way to cold here in michigan to check it right now, but the truck doesnt eat oil to bad, so i don't know

 

Do a search here because there is a couple ways to check it. Visually or vacuum.Here is the vacuum method.(which I think is better)http://dodgeram.info/tsb/2000/09-05-00.htm

 

One more thing! I know it probably won't help me getting to moderator status, and I've been wanting to say this since the thread first popped up.

Gap Change = Divorce! LOL Sorry just had to say it.

i actually just had to replace them in the freezing cold about a week and a half ago. I'll take some pics of them i threw them on the work bench

 

Ok, so I drove the truck another 1000 miles and the rough idle came back. I got fed up and pulled a plug, and sure as chit the damn thing was back to .6 gap. I am done with plat plugs went and got these instead


and the old ones....

 

what kind are they??

 

The 3923 everyone here is raving about.

 

I usually use Champions in my vehicles but have used Auto-lite with no problems. Never tried the platinum ones.
Back when we had point ignitions we figured on a complete tune up every 10 to 12 thousand miles. Also when I started driving a grease job and oil change every 1000 miles.
