The following is the only information I can find in the 1999 XJ FSM regarding idle speed, but it doesn't seem to match at all what others are saying their idle speeds are in this forum...generally around 750 RPM.
Why would the FSM give an oil pressure spec at 600 RPM and call it "Idle Speed" when it doesn't seem that there is any way that the vehicle would normally ever be able to achieve that low of an RPM?:
I'm trying to diagnose a "lurching clunking when put into drive" problem, but first I want to make sure that my idle speed is correct... Has anyone ever found the actual factory specified figure for what idle RPM is supposed to be?:
FSM page 9 - 93:
4.0L ENGINE SPECIFICATIONS:
Oil Pressure
At Idle Speed (600 rpm) ..(13 psi)
At 1600 rpm & Higher . . . (37 to 75 psi)
