    Exclamation White Smoke, Sputtering, No Power

    Two days ago on my way to work my truck started blowing white smoke and started sputtering down and sounded like it was misfiring like it went into some sort of limp mode. I shut the truck off and turned it back on and drove normally for about a mike and it started again. I pulled over and it stayed running in drive, neutral and park. I shut it off and put my quad to stock mode and I got to work just fine and it ran fine on my way home for about 5 miles and did it again I had a code for MAP sensor so I replaced it yesterday and cleaned the IAP sensor. It ran great on my way to work today all the way to work and started having the same problem about half a mile on my way home. I just installed a 5 inch straight pipe and of my awareness didn't damage anything. Could it be bad fuel, injectors, air in fuel? I have no codes or CEL. I'm lost. Below are a list of mods. I also have a short video I can post when I get the time later.

    5 inch Straight pipe.
    Built Auto trans w/ triple disc and valve body 3k miles
    7x0.009 injectors 7k miles
    Raptor 150
    Egt, trans temp and boost gauge. Fuel pressure coming as soon as this is solved.
    Quad adrenaline
    New timbo apps
    Be noise filter
    Brand new batteries.

    Any help is appreciated. Thanks

    here is a video. Trans will still shift. If I throttle more it does nothing but blow white smoke, it's not a thick smoke and it doesn't smell sweet.

    Where do you have the Quad module mounted? They tend to act strange when they over heat. Move it as far away from the engine as you can and give that a try

    Mine did that. It drove me nuts

    I removed the quad to see if that was the issue and plugged the factory map sensor in and it still did it.

    Definitely does not sound very healthy! I believe I would start by doing a manual cylinder balance test (cracking injector lines with the truck idling) and see if you can isolate the problem down to a cylinder.

    What we are primarily looking at is the difference, if any, in engine RPM / tone as you drop one cylinder at a time. A cylinder that is performing will cause the engine to run worse when you break that line loose. A bad cylinder will cause less drop in engine RPM, if any. Also, the white smoke may decrease when you crack the line loose on the bad cylinder. Any cylinder that is noticeably different than the others is cause for further investigation. Wear safety glasses!
