  1. Range Rover Classic
    Trying to troubleshoot the mysterious (yet common, if I go by past posts) intermittent surging, stumbling, idling issues I'm having on my 93 LWB, and I'm wondering if the IACV can have an effect at higher engine speeds. I replaced it less than 2k miles ago, doesn't seem like that COULD be the...
  2. Range Rover Classic
    In my 1994 RRC I replaced the IACV with a generic Chevy unit a few years ago. It does function, but the distance per step is too far. Meaning it will open the valve on engine shut off, but when it closes it, it happens too fast (each step moves the valve face too much). When cold, not an...
  3. Range Rover Classic
    My dad's '95 RRC has a high idle at start up, throws the '48' stepper motor code. I've cleaned the stepper motor (IACV) and MAF plug. New IACV is $160 so not super interested in just trying a new one. Might be a vacuum leak...never traced or replaced or diagnosed a vacuum leak before. Any...

    Hi! Greetings from Chile! I recently bought a 1992 vogue swb classic, and i still own a mint 1978 a 1975 (under a estrict resto) and a 2008 L322 supercharged From all those beauties in the garage the last 2 months i've been using the noisy 92 classic everyday without any problems at all...
  5. Range Rover Classic
    I need to purchase a stepper motor sometime shortly, and I was hoping to save some $. Does anyone have a lead on a stepper motor for cheap? Is there a vehicle that uses the same one as the Classics? With the cost of maintaining a 20+ year old rover being as much as it is, it's always great to...
  6. Range Rover Classic
    Hi All, Working on troubleshooting a Code 48 that has come back a few times after clearing. Replaced the stepper motor with a new part when it threw the code the first time. Code is triggered 15-20 minutes after running. Do I need to set the Base Idle Speed after putting the new part in. Or, I...
  7. Range Rover Classic
    I'm having some rough idle and stalling, mostly on startup. So I replaced the stepper motor with a part from a local O'Reilly. Now it runs worse! The idle seems a bit lower so it is stalling all the time now at stops. Is there a way to adjust the stepper motor? Or did I just get a bad one from...
  8. Range Rover Classic
    Hi Friends, I've searched the forums about this, but I can't really find a direct answer. I've been having high idle issues (1500 at start, down to 1000 when warmed up). It goes to lower RPMs when the A/C is turned on. I've read that it may be the stepper motor or the MAF sensor. So, I took the...
  9. Range Rover Mark III / L322
