Wonder if someone could give me a bit of advice please ? I have a 1.9 dg auto, from cold I start it by pressing the accelerator and turning the key , it fires up no problem and sits at 2000 rpm , blip the pedal and it drops down to about 1200 rpm , the problem is if I put it into gear without letting it idle for 5 mins the revs drop to about 500rpm and it does this at every stop for a few hundred yards then it's fine :?:

When it's warm kev it's around 950 in neutral and around 800 in drive if I'm stopped at traffic lights

The 'idle stabilization valve' was fitted for this and other reasons...to compensate for auto transmission drag/turning on lights/power steering/cold start transition.
However age related issues may have altered its effectiveness.

Does the choke flap have the little air-by-pass flap?

I don't know kev , I'll have a look when I get home , is it on the metal flap that's closed when cold and opens as it warms ?
