  1. General 6.0L Discussion
    I need input on an issue with my 2004 6.0L. It is making an odd revving sound when returning to idle. This issue us accompanied by a surging/loss of power. the IPR during these times is in the mid-30% range while the ICP is around 600-800psi. I do not notice any smoke when this is happening...

    I have been having an issue with my 2004 6.0L making an odd revving sound when returning to idle. This issue us accompanied by a surging/loss of power. the IPR during these times is in the mid-30% range while the ICP is around 600-800psi. I have my suspicions as to the issue, but would like to...
  3. 6.4 Motor Problems
    Greetings Everyone, I have a tune, intake, 5" exhaust, and dpf/egr delete. Runs great besides the surge/pulse on acceleration. This only happens at a certain rpm range. I think its 2200-2400 could be wrong about that ( will update to a precise rpm and mph later). I...
  4. Tranny 911
    A couple months ago my 97' F-250 5.8 (I know Its not a powerstroke but I really need help I'm only 16) started surging upon acceleration, it only does it in drive though if I manually select any other gear it is fine. It's like I'm hitting the throttle over and over as the RPM's just surge. I've...
  5. General 6.0L Discussion
    just wanted to update users about how i fixed the surging i was getting with my 6 liter. i secured the plugs for the ICP and EBP sensors so they do not rattle around. there is enough steel within 3" of the plugs to zip tie the pig tail securely to and keep them anchored and no wiggle room. i...

    I have a '99 F250 superduty with 7.3 and standard transmission. The problem I am having is: 1. A lot of white smoke at start up and continues to come out, can't drive so smokey. 2. As truck is idling and smoking, if I give it just a little fuel it is backfiring. (Exhaust is cut and missing...

    I have a 2000 7.3L PSD. While driving last week at highway speeds it would surge or buck, kind of like you took your foot off the throttle and then right back on it. it wouldn't do it with my foot off the throttle and it wouldn't do it when i would hammer it. Only when i would be trying to...

    Fairly new to this whole forums deal so bear with me on this- I've got a '95 F250 7.3L PSD, bought the truck about a year ago and the past few months it's seemed to be a worsening issue with my engine. Upon start up it kicks to the high idle feature as it's a shade cold out(obviously) but once...

    Alright - I will try to make this as short and concise as possible. I have a 2003 6.0 with 200,000 on the original gasket and studs as far as I know. Until last weekend I have had my share of problems but now I'm scared. Last weekend I had to make a road trip of roughly 2000 miles round trip...
  14. Engine 911
    Ok I posted in the diagnostics and have had no replies so maybe in here I will have luck. I have a 01 7.3 that is surging at highway speeds around 75 to 80 mph. Its doesn't make any noise from the turbo like others have discribed but I have noticed the boost will drop 1 to 2 psi. It acts like...
  15. 6.0 Motor problems
    Recently my check engine light came on and I took it to get check out at the dealership. They replaced the #2 and #8 injecter. Problem solved, but the next day it started doing something different. The truck runs absolutely perfect for a period of time and then it will start acting like it...
