powerstroke problem... need all suggestions
Hey all- I just came to this site a few weeks ago looking around trying to learn alittle more about my truck... Well now I have some issues, and could use some help from you guys to get ready to plow more snow, and hopefully save some money. But here it goes!! A few days ago it was very cold and let it warm up a bit, on my way to destination the engine was bogging and had very little power under about 1500 rpm's or more and then it felt like the turbo got hold and had all normal power. Then a couple days later I turned truck on to warm up again on another cold MN morning, and then engine stalled out after a minute; after that it was very hard to start and ran very rough and would kill after a couple of seconds. I replaced the fuel filter and seems to have ran fine for about 4 hrs of plowing, and now seems worse. I might be making an appointment w/ the mechanic today, Oh yeah I forgot More snow coming thursday and Saturday!!! yea haw!!! Any and all advice, help, or suggestions welcome and greatly needed!

Sounds like your EBPV was working when the truck felt sluggish, was it doing alot of loud hissing from the exhaust? How cold out was it? Any additives in the fuel? Sounds like you have some bad fuel, how'd the filter look when you changed it?

Filter was black, temp in mornings have been about 0-15 deg. Fuel was bought at local Holiday store with some type of additives rated at -20 deg. I didn't hear the normal sounds that I think are the EBPV, (hissing while rpms drop between shifting gears) Sounded more like the truck wanted to stall out right there and then when the turbo seemed to kick in it wanted to rip (combusting alot of unused fuel all at once and maybe not the turbo???).

No check engine light until it stalls out, or is just about to stall out. And when driving and feels like a dog there is no engine light. I wish there were a light on might clear up some of this confusion pretty quick.

sounds very much like the EBPV causing the sluggishness while driving, normal operation in cold weather.
also sounds like the stalling is gelled fuel and a clogged filter. i have found, if its cold enough even with additive in the fuel, with a clogged filter in the cold it will act like its gelled badly. throw in some anti gel, NOT 911 IN RED BOTTLE (that is to recover from a totally gelled situation, and is not a preventative additive) and change the filter. see how that works out for you.

So you think some anti gel, and maybe try to find a warm garage? It seems really weird I hope it's bad fuel. I was on Red Lake last year, true temp -30 and major winds, the truck ran awesome and the fish were biting, I wish it could run like that again.

You may have better luck running a 0 or 5 w oil ,,, maybe even a synthetic.... how may miles on the oil you're running....?

might want to check your filter if the fuel you got had additives in it it could be cleaning the algee out of your tanks, (this is what causes the black filter) if it is black again you need to load up on a double or triple dose of diesel clean. also acetone 3 oz. per 10 gallons of diesel will clean the algee out of your tanks, just keep a spare filter handy.
you can also run about 25% keroseen during the cold months for better starting, and no jelling.

Powerstroke problem
Hi people, this my first post as well, I have a similar problem with my 96 F350 4X4, 7.3 auto. It was parked since about April and never started until last Monday. The engine seems to be running on only a couple of cylinders, no power, no acceleration etc. I can wind it up in nuetral but still seems to be hesitating. I checked the turbo, that rotates fine so no problem there, also no check engine or trouble lights. I suspect clogged injectors, I filled the tanks and have added injector cleaner and have been running it for a couple of days but still no correction. Can anyone suggest something before I send it to the dealer for some hefty diagnosis charges, and also will I cause damage if I let the truck idle for several hours.
Thanks
Thanks

fuel filter needs replacing if it has sat for a long time. To check injectors take a wrench and loosen each injector line while it's running, just loosen them, not all the way off. You should notice a change in idle for each line you loosen. Do one line at a time and then tighten it back before you move on to the next one. If you do one and there is no change in the idle, that injector is not firing.

Thanks for these suggestions, I'll replace the filter first thing in the morning. I take it that on the Powerstroke engine, checking the injectors one at a time requires removal of the valve covers? Can I run the engine with the covers off?

Doh! Action is right....I was thinking of the old IDI mechanical 7.3. Electronic FI you must unplug the injector to check for that. Mark
