Range Rover Idle Air Control (stepper motor)-
AC Delco / Standard Electric "generic" replacement for Range Rover EFI Idle control.
Substitute Part Numbers also available at John Brabyn's www.rangerovers.net website.
The new replacement part has a metal body and an additional spring that my "original" did not have. I don't know if my "original" part was in fact a Land Rover part.
After replacing the valve in my 1992 RR County, the EFI seemed to take a long time to "learn" the new valve. I tried disconnecting the negative battery cable, idling, stopping, and restarting engine, and cruising at 45mph for a few minutes... the truck still wouldn't idle. The next morning it seemed OK, and idle was controlled again. It turns out that this same scenario happens anytime I unhook the battery from the car... great.
I told the parts house AC-Delco PN# 25527077 and they returned a Standard Electric PN# AC1
Also, folks have used a Borg Warner #21738
