the car ticks over fine on idle,but when you go to pull away the revs dies and the car nearly stalls and you have to hold your foot on the pedal and wait for the revs to build up for a few seconds.The car also smells very rich and is 9% on c.o. meter!Probably is over fueling. This seems to be worse when car warms up.I have lost the cat ,put in new lambda probe, set timing tried a new ecu unit and the car in general has had a full service.Has any one had this problem!Apart from all these problems the car performs very well. :?:
