2000 7.3L F-350 HPOP issues or PCM trouble???

[timberwolf]

I have a a 2000 F-350 with the 7.3L. A while back it would just die unexplicably. I would leave it sit, mainly while I tried to figure the problem out and 10-15 minutes later, it would fire right back up. I bought the AutoEngeniuty scanner for my computer and thought I could find the problem. It pointed out that the exhaust backpressure sensor was having problems and there was a KAM error. The truck did have a hypertec tuner attached to it, but no does not.

The next time the truck died, I had the scanner attached and the program said it lost connection with the vehicle. Again, a few minutes later and presto, it works. This went on for a few months, while I drove my other truck. This past weekend, I added about half a quart of engine oil to the HPOP and I cannot get the truck to fail now. While this is a good thing, it still makes me nervous and I don't trust it w/o knowing why the problem happened. Has anyone experienced anything similar to this?

What has been happened when the LPOP didn't fill the HPOP galley "enough?"
Does the PCM throw a code or just shut down? Can other scanners read the pcm in this state?

I love the truck and would like to drive it again, I just wish I knew why...

Thanks for your help...

CPS..... Did you have the recall done?

I didn't have ford do it. I bought the cps myself and installed it. The dealership here said they would have to have the truck for a week to "schedule it in."
