Fault P0170

Anyone know what the fault code P0170 means? The description is Fuel Trim Malfunction (Bank 1). I found this after a couple of "performance tests" ....

I also had a P0130 fault which was to do with the Lambda sensor ... as this was replaced in July I don't think it is terminal and just one of this blips you get occasionally from an Alfa.

Both screenshots can be seen on my Diagnostics page of my website along with the (not-so-hot) performance tests and a trace of what I believe is a correctly working MAF/AFM. I believe it works as I swapped it back in July for a short time and the replacement made no difference ... then again they both could be stuffed!

I cleared both and they haven't come back to haunt me yet ....

cheers, Gary
