strange stalling problem
Greetings -- I've had a good run of trouble free driving and it's been a while since I've posted. Just learned of the Maine chapter and joined up -- anybody from here joined up there?
Here's my problem -- my truck seems to occasionally stall while I'm driving. At speed, the engine seems to jump right back, but if I'm stopped, it totally dies, then starts right up again. It seems to be very random (at least as far as I can tell). I'm pretty unskilled under the hood, but it seems electrical? Is this the CPS problem I've read about?
Help! And Thanks!

My guess would be the cps. Change it, you need a spare anyway, then you'll know if thats it.
Get one from the dealer or IH, not a parts store, better quality.

These are the dark gray ones a lot of us are using now. Did you have the cps recall done??

Last change of the oil?
Last change of the fuel filter?
How clean is the fuel bowl vent port located inside the bowl at the top at 3 o-clock?
Any debris in the bottom of the fuel bowl?
What is the fuel pressure at the shrader valve located just below the FPR?

But the new dark grey ones, like posted above, seem to be working better and lasting longer. I keep a spare in my glovebox just in case...

The two I've replaced were purchased at the Ford Dealer. It was grey, is there a better CPS out there?

PCM connector?
Your problem sounds similar to my loose chip problem... random stall, then comes back on if the truck has enough momentum to drive the engine.
May be worthwhile checking the PCM connections to see that they are clean and tight.

Yeah, I thought about that. I wiggled the chip/pcm connection and the truck won't stall. The chip has been installed for several years. I'll keep it in mind but will probably start with another Ford CPS.
