S2 Stalling Issues

[CL11QE]

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!

well i havent tried turning the aircon on while stationary, so im not sure.

ill have to check those other things out though.

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.
