Well I have had this problem with my car ever since I got it..... It likes to drop the revs to quickly when gears changing..... lately its been hitting 100-50 and ya can hear it about to stall, although it never does.... I was told it was my computer but I recently did a 5spd conversion and swapped my computer so it cant be that.... if anything its worse with the manual computer.... I was told it was a dodgy computer because when I start my car the fan doesnt go into warmup mode for a while after the car is started.... but that problem still occurs as well... not that I am worried about that.... its the constant drops down to 10 rpm that gives me the shits, cant be healthy for the engine either... It seems to be a little better when the car is warm but definately still a problem.... I've noticed its a pretty common problem with the e-series because my mates ea does it as well, but his is nowhere near the drops I get.... I have done a few searches over the forums and cant find anything relating to the problem.... should I just increase the idle up to about 1100-1200???? We gave it a service the other day in case the oil was to thin.... but the 20-50 stuff we put in it seems to be worse... changed the oil, oil filter, fuel filter, leads, spark plugs and its no better... gonna get the timing done very shortly as it has a slight miss at idle every 5 seconds or so

Thanks

What does that mean? My clutch fan makes a lot of noise on first start up when super cold. I have somewhat similar issues to you but not as bad and have had most things triple checked. I wont bore you with the saga (plugs, leads, timing, fuel pump, fulel fillter, RON of fuel). Maybe my car wants to live in Darwin :)

On the manuals there is a clutch switch on the pedal box. It is supposed to modify the return to idle making it slower to make gear changes smoother. It does this via the ICS.

First thing to check is to make sure your ICS is working correctly, and if so, then look at the wiring for the clutch switch.
