7.3L white smoke, almost total loss of power, heavy vibration

[rjm0027]

Cruising down the highway and truck just lost almost all power and started vibrating pretty violently. Pulled over and let it idle, was idling a little rough and was blowing white smoke. Barely limped it to a local garage. Ran an injector buzz test and everything came back normal so it isn't the UVCH. Pulled the codes and got a p1280 and p0470. I know p1280 is ICP sensor could that be the only problem? truck can't even get out of its own way.

Unplug the ICP, setting the PCM to run a default value. If it idles better, then that's probably it.

Unplugged icp, no change at all, any ideas?

Didn't let it get hot and melt a piston did you? That would be my thought. If it's vibrating really bad like a miss, but the injectors are ticking, you've got a compression problem somewhere.

Could be bad fuel as well.

I don't think so no, the EGTs were below 1000 when it happened

my 7.3 did that and it ended up bing valve conections and a error in my programmer

Checked fuel today, it is good, any other ideas?
