Help... idle probs
I appear to have the much talked about idle dropping and engine stalling problem. When the engine is warmed up e.g( been driving for 30mins on a dual carriageway) and i stop at a junction,the revs fall below the usual 800rpm point and either pick up again or stall . Ive tried starting the car without the air mass plugged in and it wont start, so does that mean the air mass is fine? Ive also cleaned the air mass and the idle control valve. I even changed my vta dump valve to a re-circ because i thought that might be leaking. Please help, i've just had a rebuild and dont really fancy another one

Usually MAF, but you tested and it stalled so may be OK.
ICSV if dirty or top has moved
Air leak after MAF ...
Std ECU? If not are idle settings set right for hot & cold driving?
else as above, plugs, coil packs etc.
I get same problem if I replace my recirc dump valve ( a forge one ) with a vta one, or blank off air return at inlet and leave recirc to atmos! After a mile or so starts to rough idle then stalls at junctions and traffic lights!

I agree, very embarrassing.
Just tryied running it and disconnecting MAF, it cut out. does this mean its using the MAF signal and not an ECU substitute value and its ok?
