Motor Control Failure Update
My prob so far.
2.0 JTS (Alfa GT)
Motor Control system failure came on just after startup and continues to stay on.
Took it to Alfa specialist - ran diagnostic test - mixture lean fault - suspect lambda.
Lambda sensors have previously been hardwired and soldered (common mod I believe).
Garage reset the fault but the light came back on shortly after.
I have checked the solder connections and found one detached (soldering done by a monkey by the way). I have resoldered the connection and insulated it properly.
I have tried resetting the ecu but fault still apparent - will it need another fault reset via OBD2 connection? I have a cable on its way to me (elm327) and will use Fiatscan.
I was wondering if it was a dodgy connector then the fault would clear itself? Would an ECU reset clear this kind of fault?
Any advice would be really helpful guys (and gals).
