  1. 7.3L revs up and down at cold start ? video

    99 & up 7.3L Power Stroke Engine & Drivetrain
    This is called "Romp". The PCM is chasing the actual ICP. This can be caused by several things. Be sure that the ICP sensor is working correctly, then try a good commercially available anti-stiction remedy before you throw parts at it.
  2. put gas into 2012 F550 diesel and ran truck

    '11-16 General Questions
    08 and up. The 6.4 is just as fragile. Probably worse considering the differences in the HFCM's.
  3. put gas into 2012 F550 diesel and ran truck

    '11-16 General Questions
    What's a cummings? And Blue12 is right. Contact your insurance. Most will cover this type of damage, especially on fully covered vehicles. The whole system has to be replaced, period. Half ass it and you will be where you are again and out the parts/labor you already installed. You will also...
  4. Dealer says can't read codes cause PCM from a crown victoria

    Power Stroke Excursions
    DO NOT try and overwrite. NGS software has not been updated so it is not going to be corrupted. IT is not an aftermarket programming issue. Even with aftermarket programming, it still should recognize it as a 7.3.
  5. Dealer says can't read codes cause PCM from a crown victoria

    Power Stroke Excursions
    The current IDS software is jacked up. I've had several 7.3's that have come up as cars/explorers etc. Find a dealer with a working NGS until corporate fixes the glitch.
  6. Mystery Chime

    E-Series Vans
    Airbag Module cannot control the airbag lamp. Usually the lamp is burnt out.
  7. HELP! Need some A/C questions answered.

    1999-2007 General Questions
    Not bustin balls but some three dial control Rangers and some Tauraii did just- that ran the compressor in all positions but OFF -including VENT- when they also had an "A/C" position. Why would they treat Super Duty differently? Also why would the EVTM for 2002, page 54-2, show that it runs in...
  8. HELP! Need some A/C questions answered.

    1999-2007 General Questions
    "Vent" runs the compressor as per the 2002 Super Duty wiring manual, page 54-2.
  9. HELP! Need some A/C questions answered.

    1999-2007 General Questions
    The compressor should run in every switch position except "Floor" and "Off". The temperature blend door works independently from the compressor operation. Your compressor cycle time is too fast.
  10. EGR valve question

    6.0L Power Stroke Engine and Drivetrain
    EGR valve function is *calculated* using Barometiric pressure (BARO), Mass AirFlow (MAF), Exhaust Back Pressure(EBP), Manifold Absolute Pressure (MAP) and Intake Air Temperature (IAT1) vs IAT2 correlation along with calculated VGT operation. Basically for any given atmospheric pressure (BARO)...
  11. Crank shaft position sensor

    6.0L Power Stroke Engine and Drivetrain
    Side of the block, between air conditioner compressor and block.
  12. PATS?

    99 & up 7.3L Power Stroke Engine & Drivetrain
    You have to perform a "parameter reset" with a scan tool then program the keys. No other way.
  13. Airbag/horn problems

    1999-2007 General Questions
    If the rad is leaking, have them show you where. The horn switch is a replaceable pressure pad under the bag cover. Ok. Does the horn chirp with the RKE? Does your cruise work? No Airbag light?
  14. New CPS + IDM, no start, tach won't move. getting desperate

    99 & up 7.3L Power Stroke Engine & Drivetrain
    When you replaced the CMP, did you push it all the way in with your hand BEFORE you put the bolt in it? You have to seat the sensor all the way in first.
  15. speedometer off

    6.0L Power Stroke Engine and Drivetrain
    The chances of lifting the cab and doing headgaskets changing speedo accuracy are almost nil. The speedometer receives data from the ABS for vehicle speed. There are no cables or anything else involved. Since it works, there are no ABS lamps or whatever, I would advise you to look at your...
  16. Oil temp lower that ECT?

    6.0L Power Stroke Engine and Drivetrain
    Check your key on engine off temps before you start it first thing in the morning. They should all match. (ECT, EOT, TFT) If they do you're good. If they don't the odd man out is the baddie.
  17. 6.0L and 6.4L Ford engines reliability

    2008- 2010 General Questions
    I agree with what RT says, but you had better save 10 large for fuel system issues with the 6.4. People trade them off when they are broken.
  18. glow plug circuit problem

    6.0L Power Stroke Engine and Drivetrain
    Check the glowplug resistance and wiring at the controller connector. If it is ok, the controller is junk.
  19. 6.0L Boost differential - No two trucks are the same

    6.0L Power Stroke Engine and Drivetrain
    I have seen no mention of the fact that the 04 runs a LOT more EGR with a scoop in the passenger up pipe which also partially restricts flow on that side. The 03 runs no EBP sensor and infers VGT operation.
  20. 6.0L 4wd questions

    6.0L Power Stroke Engine and Drivetrain
    If you have a limited slip rear end there is a trick that helps to make it as useful as possible. The minimum break away torque for the clutch pack is around 25 lb-ft, If I recall right. That means it will only supply 25 lb-ft to the wheel with the least grip. That doesn't sound like much, and...
