Sounds like the engine timing is not quite right. This may be caused by a several issues, but the first thing that comes to my mind is an adjustment to the timer belt.
Per your notes, looks like you feel confident about doing the job by yourself, so I highly recommend to visit your local auto store (i.e. Autozone) and look for the Haynes Repair Manual ofr your Ford E-150. It will diagnose exactly what is the problem. There is a step-by-step guide so I'm sure you will be able to fix it.
Be safe. Good luck!
