I have a 1994 ford f350 with the 7.3 turbo diesel. i have 1000k miles and never had a problem. the other day i was out driving around. i parked the truck for about 5 min and let it idle...when i got back in to drive it seems to have a miss now. the truck idles fine but when im driving it is very shaky and seems to almost be missing and have a slight lack of power. what could cause this all of a sudden? i changed the fuel filter about 4 months ago. the truck is not a daily driver. probably gets used about once a week on average. im not sure where to start?? i looked underneath cause at first i thought maybe a broken spring or shock cause im feeling a lot of vibration through the shifter and seemingly the rear of the truck?? could it be fuel related or injector? any help is much appreciated. thank you!
