What does the 4.0 OHV idle at?

[B30004X4]

How many rpms is the 4.0 OHV supposed to idle at?

There is a decal somewhere under your hood that has that information

Typically 700-850 depending on year and transmission (auto or manual)

the truthful answer for most 4.0s is wherver the ecu feels like idling at that moment

 

[Ranger#1]

yea really that is true

is that idling in park/nuetral?

i've noticed 7-800 rpm idle in drive, when standing still with my foot on the brake and 1000rpm idle in nuetral.
