If anyone can help with this problem they will have succeeded where the main dealer and independent specialists have failed.
My '02 800cc Matiz's engine intermittenly cuts out when the revs drop, such as when slowing down at lights and junctions. It restarts immediately but will only continue running if the revs are kept up. If driven in this condition it is fine under acceleration, lurches like a kangaroo when on steady throttle cuts out again when revs fall. This will persist for 3 - 4 miles and then it will suddenly clear. In addition, the engine management warning light is on constantly, even when it's running well.

Just about every sensor has been replaced or substituted, including the ECU. The injectors have been changed, as has the inlet manifold and the engine wiring harness. Sticking valves have been suggested and ruled out. Electronic diagnosis gizmos seem to come up with a different code each time they are plugged in.

I'm at my wit's end. The car has covered just 29,000 miles and in all other respects is in excellent condition. I want to sell it but unless a solution is found I'm faced with having to scrap it. Any suggestions gratefully received.

sounds like coolant temperature senser has failed and probably the lambda as well has been killed .
a co test would confirm the lambda .
