Lamda sensor wiring.

Hi guys. An update to a previous thread.
I have the Motor Control System failure warning light (54 reg Alfa GT 2.0 JTS - 60000 Miles)

Took it to an Alfa specialist today who hooked it up to the diagnostic set. High fuel mix under load or words to that effect.

He looked at the wiring for the lamda sensors - it looks to have been modded and has been soldered with the car end plug being removed and 'hard wired'.

He suspects this is the cause. He reset the faults but it reappeared shortly afterwards.

Is it a case of checking the connections? What else can I do? I noticed some of the solder is exposed should I just insulate them better?

Is there anyway of resetting the fault codes without a diagnostic reader (elm327 or equiva;lent)

Cheers guys

Re-make the connections, and put some shrink-wrap tubing around them to keep them insulated. Sounds like someone has botched the wrong probe onto the car though.

You can reset the codes with FiatECUscan (free) or AlfaDiag (not) and a suitable lead.
