Hi All,
I've had a long standing problem with my car in that it sometimes stalls coming up to junctions. As far as I've noticed, the fault usually happens during the warm-up phase and occurs when I change down gear i.e. the revs overshoot the idle point and the ECU can't recover it.
I've tried to get to the bottom of this for a while to no avail - a change of both lambdas have reduced the frequency of the fault but it still happens occasionally. The idle is a steady 850-900 rpm when warm but when revved the overshoot causes it to hunt for a second or two before it stabilises (it's always done that since I bought it in 2006).
The car has a contactless TB, 2 new lambdas and a new temperature sender fitted. I usually keep the car with the battery disconnected, as I don't use it as my daily drive, and have wondered about the effect of this on the advance/retard setting of the ignition..... Also, normal operating temperature is about 70C so the thermostat could be due for a change.
Any ideas?
Thanks,
Steve
