My question is this i hope someone can help i have tried everything i can think of i have a 1992 F250 supercab 351w the vibration damper on it broke so i swaped it out however i used a damper off of a older engine after i did this it started running for a lil then shuting off i have seen that the damper that comes on the 1992 has a 4lobe pules ring in it that interrupts the magnetic field to the cp sensor i know that the older damper was made bigger then the one that came on the truck can this be causing my problem with my truck shutting down after 30min's untill it cools then it cranks again an runs fine for another 30mins i'm stumped please help if ya can
