  1. By open do you mean assembly extended or retracted? After having a google and checking photos, at rest they seem to all be retracted. I managed to get the assembly to move by brute force, so extended it slightly, then refitted it. The idle is now at about 750-800, so I'm guessing that is where the fault would lie. The idle hasn't been right for a while, even with it connected to the MS2, the idle would never change from warm up to normal temp. I am using the standard 4.6 plenum. Thanks for the reply I am going to order a new valve and see what happens. It is quite possible the valve was done for as the car I got the engine from had been stood for about 18 months.
  2. I'm having a problem with idle on my MS2 setup on my 4.6, basically it's running about 1500rpm, sometimes creeps up but generally doesn't drop. I've had the idle valve unplugged and nothing has changed. I've removed the idle valve today and there seems to be very little movement in it(maybe about 1mm). Would I be right in assuming that it is fubared? The coil also buzzes nicely when I plug it into the MS2 connector with the ignition on, which I take to be a sign that it is drawing current but not doing anything.
  3. Took it back up on Wednesday and the ppm was under 100 but the CO was around 5% AFR on their machine was about 13:1. Back up again today after dropping the fuelling around the level that they test at. Will take laptop up as well so hopefully can make changes and get it sorted.
  4. Cheers for the pointers, I'll get out and play with the fuelling when it stops raining here.
  5. Ok, so I finally managed to get the disco MOT'd to check it over and see if it was worth throwing more time and money at. On the whole it wasn't too bad, a couple of lamps and the ABS light is on. The main thing though is mixture and to be fair I haven't had much time to get playing with my MS setup, other than getting the engine running and sorting out TPS issues. Attached is the test sheet, and it looks to me that it could be a case of running slightly lean? My disco is a 95 so is running cats, which I suspect are knackered as the right hand bank has a rattle in the exhaust and I'm not sure my lambda sensors are working properly either. I have bought a new one off Nigel to fit but as yet haven't got round to it. Am I going to be better off replacing the Y piece with the cats and starting from there? Is there anyone local to me, near Tadley, who has had a bit more experience with MS than I have?
  6. I've recently done this one a 4.6 GEMS, I just used the plug on the loom, using an MS2. All is working fine, if you have the GEMS ECU connectors still attached the pin outs for the ignition coils can be found here http://www.rangerovers.net/forum/7-range-rover-mark-ii-p38/44978-lucas-gems-engine-management-ecu-pinout.html
  7. Excellent, thanks for the help guys I'll get on and swap it over asap now.
  8. Yes but there is a port, highlighted below, and when I blow on it air comes out of the port for the idle valve
  9. Having recently fitted a 4.6 engine as my old 3.9 was knackered with liner issues, I refitted the 3.9 plenum on top, which I now realise was a silly idea as the TPS is on it's way to failure and they are a ridiculous price new. I still have the 4.6 plenum, and as I am using a MS2 ecu changing the wiring doesn't pose a problem, my only issue is where does the hose for the idle valve go to?
  10. Yes post 95 is slightly different I think, sorry I didn't see you post last night. I'll do it when I get home, but might be later as have my kids to drop back and the stepson to collect. Jon
  11. Just make sure you have the right USB lead, it's not the standard type A rectangular on the serial converter by the looks of it, you would need a type A male to type B male. These leads are quite often used on printers and other USB accessories.
  12. In terms of leads, you would probably be best off just buying a 9 way to 25 way RS232, and get each end to match the gender, the 9 way would then plug into your USB converter and hopefully Bob's you uncle and Dick's a close relative. RS or Maplin would do these, or I suspect Fleabay. The diagram on the last post of the thread you linked to gives you everything you need to make your own cable though
  13. No problem, thanks for sorting them sooner than I could If mine are still needed just let me know and I'll sort them.
  14. No problem, I normally get back around 6ish so will sort it then. Jon
