Symptoms... I've got symptoms
Bought new in 2005, my "Chateau" E350 with 6.0 is completely stock. The engine has just over 200K miles, and both it and transmission have not been opened.
In 2012 I did replace the FICM, and it ran well (with a couple of leaks) until the end of March 2017.
Now, it is dying on the road, and requires a lot of spins to restart. Here is what I know!
1. When cold, it starts easily after a fairly long lean on the starter
2. When warm, it may or may not die while idling, or while on the road. More later...
3. When hot, it runs well, and I have taken it out of town with little fear of it dying
4. When warm, a quick turn to either the right or left will often precipitate a stall, actually I have to go quite slow to guarantee it will keep running
5. When warm, following a stall, the engine will restart after 5-8 attempts to start. Usually, it will start to turn easily after a while, but die if the starter is released. This will be repeated several times, before it gets up to 700 rpm and stays running. A quick blip of the pedal then makes it appear that nothing happened, and I can get back on the road.... until the next time. The next time could be 100 ft down the road, or not until the engine goes from cold to warm again.
I took the van to a good local shop on three occasions when I first experienced the stalls. They were never able to duplicate my problem, and didn't want to work on it without experiencing the failure.
So, I kept on driving it, and compiling experience about the stall, and kept narrowing the experience. For example, at first I though it had to do with hills, incline and decline.
After a while I realized that the inclines and declines near my home where the engine stalled were out of curves. (It still may have an incline problem, but it is far less sure than the curves.)
Now, I have again replaced the driver board in the FICM (not the entire FICM), to no change whatsoever. Not worse, not better!
Then I disconnected the ICP. Maybe it starts quicker when cold, but that's all, if it isn't my imagination.
NOTE: I'm getting pretty good at nursing this thing alone, but I'd like to get to the root cause and fix it!
