06 cobalt 2.2 sc with man.trans. lack of power
Lags or hesitation. Was
intermittent now is
constant. Has set
p0171 code and had
p0133 pending. Live
data looks for the most
part normal . Fuel
pressure 60 psi at all
times while driving. Maf
looked low and
appeared to be
flickering watching it on
a graph. Tried a new
sensor with no change.
Can't find air leak . Tps
looking steady. Map
also looking normal. It
feels like a lag in the
super charger boost.
Belt good no noise out
of it. Changed oil in it .
Got 3.2 oz out and put
3.2 oz new back in . 1.5k
on this car and that oil
didn't look bad at all.
Still had a goldish color
.I have seen this oil
black as coal. Anyway
didn't change anything
servicing it. Still lagging
