Yep, even if it doesnt have an electric sender from the gearbox there is still a vehicle speed signal.

On a cable driven setup the pulses come from the back of the speedo its self and is sent to the ECU from there

LEE...s speedo is cable driven, not wired with a sender (1994 1.4 16 valve model)
would this still be the problem?? i can see why if he had electric clocks but he asked me before and i didnt get how a simple speedo cable could cause this problem

im probably wrong mind?? is it just a case of replace speedo cable?

Without the speed signal the ECU assumes the car isnt moving, so when you use your engine to slow you down with no throttle at 2k+ RPM then the ECU thinks theres a problem that the car is idling high. Then closes the idle valve and never re-opens it so you stall a lot.

Till you fix your speedo you can stop it happening by not using engine braking above 2000RPM

ah right i see, well i keep trying to fix it whats happend is the cable has snapped at the gearbox end and the thin needle wire bit is stuck in the gear part on the gearbox so all i need to do is pull it out to get a new one in,but the wire isnt sticking out of teh whole so cant get any pliers or out onto it, so was thinking maybe a magnet? im going to give it a try tomorrow,anyone else got any ideas? thanks lee

I think it is something to do with the transition period from ECU control to ICV.

ah right so its true, thanks for that il get it sorted asap now cause its doing my head in :)

Speed sensor on the clocks or the speedo ring in the gearbox.

get your speedo sorted and the problem will go away. someone will be along shortly to explain what is happening......all i know is i've read about this many times on here and the speedo was the problem.

as title my car keeps cutting out coming to a stop at traffic lights e.t.c its a corsa sri 1.4 16v x14xe engine 95 model what it does is when your slowing down to lights and put the cluctch in rather than going back to idle it will cut out and sometimes wont cut out but the revs bounce to 0 then 800 and then settle normal its starting to really annoy me now, iv been told it could be the speedo cable bit its not electric its a cable and it has snapped but i dont see how this could make my car cut out?, it runs spot on all teh time apart from when your coming to a stop its just wont idle properly first time, ive just put an icv and lambda sensor on today off a mates engine and its no different:9 sorry for the essay any help be great :) thanks lee
