hey all

noticed something irritating recently - as i pull up to a set of lights/roundabout etc, the car, just as its about to stop, feels like its about to stall :? it hasn't at all, but its pissing me off, and was just wondering what people might think it is?

i'm thinking of resetting the ECU, resetting the base idle, and cleaning the ISC - any other thoughts?

cheers

could be something to do with your vacuum tank - which generally purges as you use the brakes...

Can you please explain this?

How is it purging and from where?

Why would it need to be purged?

Cant see how that would happen. The brake booster is much much larger than the tank. Plus it has a one way valve in the engine bay to stop the tank being emptied.

I would guess the base idle maybe too low, or the isc is slow to react. If I stamp on my brakes hard when i get to a stop the revs dip low. But the isc is working hard to lift the revs back up. But it never stalls or feels like it will stall.

Thats why I asked the question, it didn't seem to make much sense to me either.
My understanding, the vacuum tank is only to maintain vacuum to the heater controls

Eggzarcary... To maintain heater controls at WOT and the engine is not generating vaccum.
