Check out your air filters carefully. On my 06 with the 8 cylinder engine it had 4 filter canisters. Also the plenum chamber itself
that connects them all together was almost completely plugged with nearly 40 years of crap. Usually have to take it down to get it cleaned out. 06 Bill

So I took the plenum out. And it was completely clogged with greasy sand and dirt (felt and looked like clay). So I disassembled it, cleaned it, put back in. Started it up and took off down the road. Same symptoms, no power. Checked the intake pAssage ways, nothing found. I left and bought a can of "Sea FoAm". Put it in, lots of white smoke, took it for a ride....and it seams to be fixed. I'm not Quite sure whAt the problem was, but I guess it doesn't matter. Comments welcome. Thanks for the help.

You have a fuel supply problem your filters may look good but it does not take much to slow the flow get the fuel flowing the black smoke will go away and the power will increase.
good luck

Where did you put the Seafoam? I always though you put that into the carburetor?

Sea Foam is actually one of those snake oil products that really works.

Here is a link to the sea foam home page. Tells you what it is, how it works, and has a link to find where you can buy it.

Pardon my skepticism, but I truly do not believe that anything you put in your tank fixed the problem.

I have to agree with Len, that stuff is like all the rest of the snake oil treatments, it does no harm, probably but it also does no good. Solvents mostly, which may knock loose some crud, something almost any diesel fuel treatment will do.
I looked at the web page, not a word about how it actually works. Many words about what it does though!!
If it is original you have three oil bath air filters above the engine. These can have varmint nests or be overfilled with oil.
The nature of the oil bath system involves the incoming air pulling oil from the bottom reservoirs up onto the side of the inner metal mesh filter. Too much oil will cut off the air.

I really have to disagree. I have had great success with Seafoam in many different things and it seems to be a pretty good product. Granted it may have not magically cured this problem but then again it just did. I've had similar results with it. It's cheap, doesn't do any damage and I've read about it on many other forums from bikes to car buffs. Take my opinion for what it's worth.... 2 cents! Later

John Deer dealer here told us to use it in one of our mowers to help solve valve train problem...said try before tearing it down....very skeptical but about 40 hrs later that unit is running OK....don't think it will last but got more production out of it at a busy time of year...Sea Foam?snake oil? positive outcome this time...still don't trust or understand

At my Deere dealership my Parts Manager swore by Seafoam, and he sold a ton of it to customers! I have a TDI Jetta with almost 300k on it. One of the lifters was a little noisy on start up for about a minute. He dumped half a can in the engine oil, I ran it for 5k miles, and the noise went away. It's been gone for 50k miles now. I used it only that one time.
Now, I've never tried it in diesel fuel, but if cleaned up that lifter, I would think it could clean up an injector, even if just a little bit!

Old DD mechanic here swears by it. I have used it in many problem engines and it works.
