Noticed icp was was saturated with oil, chaged it and wiring harness. Truck ran great till coming back from deer hunting, stalled out completely at a stop sign, restarted and drove 200 plus miles with no issues. I hae been chasing this for 8months. I am heading to the shop tomorrow to see what else. If I find the problem I will post for ya. I know lots of 7.3 ae having the same exact problems but no one has the fix.

Rick There are a fair amount of differences between the OP's and the 1999.5 and up models. |

Showtime, ford has some recalls on some sensors you may want to look into. Not sure if it will fix your problem but worth taking advantage of. I will let you know what fixes mine to save you some steps and money hopefully !

A bad PCM will shut down one bank of cylinders. The PCM sends the injector signal to the idm which converts it into an a/c voltage to fire the injectors. Also check the harness over the drivers valve cover. Just below the big square connector sometimes the harness will chafe and short.

I've been on the power stroke forum and there are lots of people having the same problem showtime and myself are having. But know one has the cure!!! Rick |
It can also be the valve cover harness, the loose connection is on the INSIDE of the valve cover, someone said they made sure it was tight at valve cover, but did they pull the cover? the oil will make the locking tab weak, makes the truckm do all kinds of crazy things, I used a wire tie to lift tab to lock so it is impossible to loosen, was cheaper then a new harness...
