Strange stalling problem

Member
As some of you may know, I have been told that I will be redundant from my job of 15 years on September 30th.
In an effort to keep my spirits up, I have been using my 944 turbo daily to do the school run and other small jobs. Well yesterday, I was forced to go back to the office (62 mile trip) to clear my desk.

The car ran faultlessly for most of the journey that involved the motorway, but after I left the motorway, things changed.
Whilst negotiating some small B roads, the car suddenly lost all power, no warning lights on the dash, just nothing when I pushed the accelerator pedal. The car was still rolling at 50+mph and I let it roll for a while and then tried pushing the accelerator again. After a few tries the car began picking up speed again.

On the way home, I had a repeat of the above but this time after leaving the motorway and trying to negotiate a cross roads. In the distance a skip lorry was approaching and I thought I could beat it across the junction. When i tried to pull away, the car stalled and wouldn't start again. The lights on the dash were as normal when trying to start the car and the turbo pressure gauge was at 1bar. The car would start fine, but then stall instantly. There was a smell of fuel from the car.
I pushed the car backwards out of the way of the skip lorry, but nearly into a ford transit behind

After waiting in a layby for a few minutes, the car fired and everything was normal. The car has performed faultlessly since, but i am frightened that it could let me down again soon, perhaps in a less fortunate location or perhaps with the children on-board.

any ideas what i should check? The car has been serviced recently (late last year) and done less that 2k miles since. I dont think that i have checked the dizzy cap or rotor since i bought the car, so i will check those asap - well on sunday.

Any help appreciated.
 
Make up a three way DME bypass cable as per Clark's. If it runs fine with the bypass in then it will be the DME. Remember to remove the bypass when you have finished though as it is a constant feed.
 
Sorry, DME relay should, of course, be the first thing to change. I get very complacent after all the years of banging on about carrying a spare, and I just assume that everyone either has a new one on the car, or in the car! [:D][:D]
 
I have an idle issue on my S2 but yesterday after fueling the car would not Rev and the rev counter needle was bouncing all over the place. Turned off and it restarted and ran a bit better but wouldnt pull on pushing the throttle, would gradually build up speed, got home let it sit for 15 mins and its running fair again, still at times wont idle and i have planned to clean idle control valve but you got me thinking, could it be the DME relay?

Sorry to highjack your thread

PS New idle control valve is £356 yikes
 
Well its not the DME in my case. forgot had new one lying around, fitted it today and still got erratic idle.[:(]

Back to plan A remove and clean idle control valve[8|]
