[SEL] OFF TOPIC: THANK YOU Read at your own risk. Old Ford 5.8 liter 351 Windsor Engine Problems

[Mark Shulaw]

Hi All, The diagnosis is in. The final solution was the PCM ( 
Powertrain Control Module ) was at fault. A capacitor was bad on the 
board. I repaired the board with a new capacitor of the correct 
rating and reinstalled  the computer to find a great running engine. 
No more stalling bucking stumbling or spark knock. The only absolute 
problems was the fuel filter and the computer. You can see the repair 
at my face book.   Thank You to all who replied!!   The support of 
the list is great.    Mark
