please pelp me out
what do i have to replace?
the engine sign come up 2 days ago,
scaned the code:
P2096 post catalyst fuel trim system too lean Bank 1
what does that mean?
after the driver side cat slow fuel trim?
what fuel trim? why does fuel has to exist after the engine burned fuel ?
i dont get it
some have replaced all 4 o2 sensors, exhaust and the code came again.
the problem is
if there came p0420 & P0430, means bad cat or exhaust leak
p0137 and so on would be the o2 sensors
