– Check visually
for air leaks be‐
tween intake
and throttle
body, oil fill cap
not tight or oil
dipstick not
seated in tube.
– Also visually in‐
spect any en‐
gine gaskets
that can cause
additional air to
enter the crank‐
case can set this
fault as the PCV
system is not
metered. If a
vacuum leak or
crankcase gas‐
ket sealing is at
cause, the idle
may be rough or
unstable.
– Check the In‐
take Manifold
Sensor - GX9- .
