    I have a 2000 international 4700 with dt466e that has code 333. I replaced the ICP, IPR, HPOP, CMP, injectors were new last fall and pass the air test.All OEM parts. it has a miss when hot and blows smoke once the smoke is cleared out it runs better. it runs great cold. it use to take all day to act up now just 20 min it will act up. if the truck is turned off and back on it runs good for awhile even hot. any ideas???

    So that code is the ICP is not able to maintain desired by more than 400 psi plus or minus for longer than 7 seconds. It would be great to know if you have pressure too high or too low.

    Simple things first, check your oil level.
    Any other codes?

    You would be amazed at how many DT466E and Cat 3126's got towed into the shop I worked at, topped off the oil fixed them. :violent1:

    How worn is the injector pass through connector at the valve cover?
