Possible Manifold issue
My air went out on my 2008 pontiac G6 and the
temp gauge doesnt move. I decided to get the
codes read knowing I at least needed a
thermostat. The codes came up P0420, P0010,
P0128. Do you think the manifold and or gasket
need to be replaced or could it just be the thermost
at and maybe 02 sensors?
