I've been noticing over the past week or two that my Stagea has had slight rev issues but they

werent really causing any problems. However just over this weekend on two occasions the car

stalled. Both of these times i was stationary and turning the wheel, so when i got hope i tried it

in the driveway, and turned the steering wheel and it stalled. It doesnt seem to make a difference

whether the car is hot or cold. I have a 99 Stagea RS Four S.

will it do it with the aircon on too?

might be ICV (or whatever its called on an RB) or your throttle body could be a little choked up with oil and needs cleaning.... also clean AFM while youre doing that!

try it with the aircon on, the idle control valve will open (or close - i can never remember which) depending on load at idle when you switch stuff on, like aircon, or turn the wheel and the pump loads up.

also, check your spark plugs seeing as the bonnet is up and the throttle body is off :)

is it hunting a bit at idle?

another quick cheap thing to check there could be a simple vacuum leak from one of the many small vacuum hoses. the small one at the front of the plenum is a classic for a small split but it is worth checking them all.

My RSfourS has both Boost & vacuum to p/s load switch above power-steer pump, 1x straight boost off t-piece near std boost controller, 1x manifold vacuum and goes to never-never!

Have you disconnected battery recently?

IAC idle valve does gunk up over time but ecu compensates, If you've reset ecu then it goes back to factory settings with gunked up IAC valve.

Sometimes takes weeks of normal driving to sort out or quick 5 min ecu-reset/idle-reset procedure, even power fc manual stats it!

disconnect batt - start to operating temp, idle no loads at all, one at a time - low beam then high, a/c on, steering load, wipers, lighter, radio, etc - then all on at once.

    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position. 
    • You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
