Problem with my 2005 Chevy Equinox
V6
dash lights = Check engine light
GM Computer codes = p0171, p0496
Repairs done prior = Had an oil change.
Had the codes scanned at Autozone.
GM tech = jk
question = My check engine light came on a few days after I had an oil change. Had the
computer scanned for codes at Autozone and came up as p0171 lean, and p0496 evap
system purge or something. What are some common causes for this.

JK:
The code p0171 is a common code to turn on a check engine light after an oil
change on this vehicle. If the oil change facility checked your air filter, then most
probable cause for this code is that they have accidentally disconnected a vent tube.
This tube goes from the air intake duct on the air filter housing, to the rear valve
cover under the ignition coil / module. (see pic ) Just reach under coils and plug the
hose back into the top of the valve cover.
P0496 is described as "Evaporative emission system purge during non-purge event"
This is usually caused by a faulty purge solenoid. Under the engine cover, on top /
passenger side of intake manifold.
