Hello,
I have a alfa romeo mito 1.4 t-jet (120PS) with A LONG TERM FUEL TRIM of -22.
Sometimes it gets to -25 and throws a P1172 code.
o2s1 is around 0.8V and o2s2 is around 0.4V at idle. I changed the o2s2 sensor and nothing happend.
Intake manifold pressure: 34 kpa.
P.S. I know it is a fiat site but they have a lot in common
