Archived major loss of power

[diesle_redneck]

I just bought a 99 2500 from texas. It has the six speed transmission. Anyway, today coming home from work in 10 degree weather, the truck runs normal below 40 mph. But once i get on the highway past 40 mph, it sounds like the engine sputters, i look in the mirror and a whitish blueish smoke is coming outta the exaust. Now I have the darn thing floored and can hardly make 60 mph and on hills forget it. I just blocked the front grill off with cardboard as much as possible, I thought maybe the air is to cold for the engine to run, but nope, she still does it. Any help/suggestions would be very helpful, i need the truck for the snow tonight!!!

Sounds to me like you have a filter plugged. Perhaps you should change it out, then see if you are running better. I had this basic thing happen on my 94' some years back, and found there was water and debri in the filter element. I found this out after I tore the filter apart.

One other possibility is that the timeing has slipped a little. This can also make the engine do the same thing.

Good luck!

Agree, change the fuel filter. The same thing happened to me in upstate NY. Kind of comes on slowly as the filter waxes up and I had Power Service additive in the fuel. Led me to install a post filter fuel pressure gauge to keep an eye on things (that's when I found the lift pump marginal also).

If its a 99 its a 24 v. The timing doesn't slip as the pump gear is keyed to the shaft (unlike the p-7100 equipped 12 valve's).

Bubble boots...

Double check each of the 4 rubber "bubble" couplers between the turbo and the intake manifold - 2 on the passinger side, 2 on the driver's side. They need to be pretty tight - plus stuff can rub against them and chew a hole in them sometimes. Spray with hair spray then slip into place. Helps it going on and seals once there.



If one of them is loose, it won't let you build sufficient boost pressure to give you the power your used to. The problem (leaking air) could get worse the more you lean in the pedal. This would explain the loss of power.



This would also explain the whiteish blueish smoke as well. There's not enough boost/air to burn all the fuel your dumping into it.



Let us know.

I would have to agree with Ben, but if that is the problem your truck would sound like a GIANT INDUSTRIAL VACUUM cleaner. Most likely its the fuel filter, but if it's not that definetly check those intercooler boots. I had the EXACT same problem a month ago execpt the I was getting the above mentioned noise.

Fuel Filter first; or possible problem with lift pump

Don't know how many miles you drove with the Texas diesel in it but maybe you need some blended fuel for the colder temps. Most colder climbs go to a different fuel blend in the winter months to prevent waxing up. Check filters and add some DFS.

thankyou

Thanks guys... . plugged fuel filter, changed it out and it runs like a dream. Glad I subscribed to this website, well worth the money.
