  1. 94-98 7.3L Problem Forum
    Hey guys, I have a 94.5 7.3 F350 with a ZF5 and 4.10 gears. For the past year or so when I hit 70 and about 2500 rpm it will do a jolt, like you shut the key off, or all fuel was cut off for a split second. Basically like if you turn the key off and on like on a gasser. Split second is all...

    Howdy! I'm new to the Power Stroke forum and a new owner of a 2004 F-250 with the 6.0 diesel engine.

    I have found lots of posts chasing around various issues with Loss of Power & Rough Idle. I have read all I can find hoping for an answer but as of yet I have found none, with the possible exception of either 2 bad injectors or a shorting Fuel Injector Harness.

  7. 6.0 Motor problems
    A few weeks ago my truck lost power and boost went all the way down. I could put it WOT and once it got to about 50 or ore it would build boost and take off. I changed fuel filters and put injector cleaner in and it seemed to be ok for a little while. The other day it stopped building boost all...
  8. 6.0L Problems Forum
    My truck randomly lost all power and went to idle four times in a matter of 10-15 minutes this morning. When you hit the accelerator it does nothing. I have to shut the truck off and restart in order to "reset" whatever is happening. After the fourth time doing this it ran fine for another 20...

    Now that its finally been cold here in Missouri, I've noticed that on the cold mornings (or simply from sitting all day outside during work) my truck will put out a little white smoke and feels very sluggish.

    I have recently purchased a F250 7.3 for pulling my camper. My camper weight is 10,000. Took it out for the first time this weekend and had some major issues.

    OK sorry if I offend anyone with my lack of knowledge here but please help! I had not driven my 2000 7.3 for about a week. I had it plugged in for a while and started right up as usual.

  13. 99-03 7.3 Motor Problems
    Ok so two months ago I noticed a howling sound only while under heavier acceleration and seems to have a loss of power. I replaced all CAC boots and it is still there.

    I'm looking for help diagnosing a problem we are having with our 2004 PSD I'm fairly sure it a turbo but thought I'd pick yawl's brains and see what you think.

  17. 6.0L Problems Forum
    At first I thought it was a bad injector, (no smoke of ANY sort) so I threw in some injector cleaner/octane boost. The symptoms went away, about 50% better. Still a loss of power and at about 70km there is kind of engine surging. If I take my foot off the throttle and step on it if goes away...

    Lots of good post and replies, but none found as of yet for my problem. I have a 2004 F350 6.0L work truck that has been getting worse over the past year or so with fluttering under power. It sounds the same as when you let off the throttle after pulling hard, but in this case it's while you...
