Now that you have CSIPSD's attention, listen to him. Be careful running with no bed, hood, or fender. Like he said, what color smoke?

sorry, just missed that.

Need to get someone that can read and clear codes, maybe do a data log and watch the ICP pressures and duty cycle. Also do a cylinder contribution test and a buzz test.

Any excessive blow by?

I have made some progress but still not quite there, I believe it has to do with some sensor or switch because it starts great now smokes a little and then it seems like a switch or sensor switches on or of and it starts missing and smokeing (still light color) itdid smoke dark after I started it after changing injectors,anyways I started checking sensors by unpluging them to see if anything changed and then I think I found the issue or at least one more the thing called ipr ( injector presure regulator) it is missing part of it self and it spins freely on the shaft I think this thing may make it run to rich? so I ordered a new ipr, as far as blow by I dont know how much a 7.3 motor should have but it doe's have blow by but again if it is running as rich as it seems to be I would think there would be more blow by? as far as driving it half naked I live in a rural area so not to many folks out this way if I lived in town they would have already hauled me off.

In your first statement, you said you changed the oil filter. Did you change the oil? Oil is absolutely critical in a powerstroke. Did you do the reading I suggested?

The outside of the IPR will spin freely. Is the little tin nut still there holding it on?

Hello again , I strugle with reading have a brain eye disconect of some sort so I don't read much. Yes I now have changed the oil 2 times with maybe 2 hours of running time it seemes to start fireing on all cylinders after it gets up to temp? the ipr thing doe's spin freely but the collar and the nut are gone and they look to have been gone for a long time the inside of the magnet part is worn and when this thing is running you can move the part that spins and it changes the way it runs almost like a vacume advance on a distributer? like I said this is all new to me and very interesting and frusterating at the same time.
Thanks. Jack S

You need to get that tin nut on. See if it is still in the valley or get to the hardware store. I put threadlock in mine because it kept coming off. I think it was over-tightened once.
