Can someone help please.
The engine management light come on my focus st170. I took it to some garage to have a diagnostic check. He said its coming up bank 1 and 2 sensors and intake control runner box. So i got 2 new lambda sensors and a control runner box. Fitted them took the battery off to re set. The light went off. When i started it there was clouds of smoke which filled the street so i guess they worked fine. I let it run for a bit turned the engine off and back on again and the management light came back on again. When i took it for a drive it was cutting out when i was about to stop.
Any reason why its cutting out ?
And have i got to take it back to a garage to get the management light re set ?
Cheers
