2000 4.0 4x4 xlt idling problem
 

New to the forum and rangers. Picked up a ranger for cheap but had a weird idle problem. I found this guys video that shows exactly what my engine is doing.
https://m.youtube.com/watch?v=FRDNVYccKn8 He comments that it was his gas tank but I'm guessing fuel pump. anyone else have this same problem and fixed it? Also, I apologize if this has been posted before and answered. I searched a lot before posting.
