Wierd Stalling?
On my "97 Superduty the truck will stall first thing in the morning after driving for 15-20 minutes & then not start back up for another 15-20minutes. The mornings I let the truck warm up for about 30 minutes before I leave it does not do this. Several mechanics have tried to solve this puzzle but failed. Supposedly it is ignition related but I do not know. So if anyone has any ideas about this please let me know. It has been this way for about a year & is driving me bat$h1t crazy!

The PIP sensor (stator pick-up) & the TFI module (IDM/ICM) are both temperature sensitive on their way out. The TFI module will not show on an Error code scan, but can be bench checked at places like Autozone. The PIP will show up on an error code scan, but requires removal of the distributor to replace. The symptoms are identical when either fail. Their functions are so closely related & life expectancies similar that they are usually replace at the same time. Pip's are $12-20 by itself and some people just replace the distributor to save labor (which includes the PIP) Ford Fuel Injection Stator (RPM) You might also run it by a muffler shop & have them check Cat backpressure. It only takes 3psi of backpressure to stall out an engine. That's a Cat temperature thing. The little b@stards get red hot when they restrict. When they cool off, it runs again! Under load's what pisses it off, especially a bit of a grade. Something to consider. I found out the hard way.
