engine not idealing properly

[mischief]

iv got a standard saxo vtr 52 plate and get it fully serviced every year.

for some reason when i come to a stop (ie waiting at traffic light or parking) the engine dosnt ideal properly it drops until it almost stalls then revs up again and dose this a couple of time before idealing normaly. the wierd thing is it dosnt always do it, just when it wants to it seems (car is perssesed or somthing lol):S

mine does this too, does it when you tap accelerator pedal. Just rev it slightly and it stops.

yer if i give it a little it stops and that sounds like promising advice cheers:y:

Sounds like its having a fit, my gbox has just gone so this is least of my worrys >.<

[mischief]

just looking through my haynes manual is it the idle actuator valve?

[Icey_Furio]

Sounds more like the coolant sensor to me. it's temperature dependant, so it doesn't do it all the time.
