ive seen alot of 4.0's go past 250k without much maintenance besides oil changes. i would check the fuel pressure regulator, and i only say this because when i swapped mine out it was full of black gunk, and it made a world of difference.

ive never had a 4.0 that asked for much, but ive always bought atleast 1 new sensor every payday or tried to every month till i had all of them replaced. even tho it seems to run fine, it couldnt hurt.
