Hi,

I have a 2015 Fiesta SE sedan 5 speed with 94000KMs. When doing some diagnostics for something unrelated a while back I noticed that my long term fuel trim was quite low at idle. -7.8 to -9.3. I know that's within "normal" values but more recently I've seen it go as low as -10.9 at idle.

STFT stays around 0 and at speed LTFT goes up to between -3 and -5.

Is this something I should be worried about?
