02 camaro lean code problems i have an 2002 camaro 5.7 ls1 6spd
all stock other then the SLP upgrades
trying to get the car to pass inspection etc..
but the SES light stays on due to P0171 and P0174.
i have already replaced the Mass air flow sensor and was wondering if it would be both pre cat 02 sensors or if anyone has any thoughts..
willing to try anything..

You most likely have a vacuum leak. With the engine running,can you hear any loud hissing sounds in the engine bay? Its common on these cars for the pcv hose that goes into the intake manifold to leak. Its in front of the pass side head and goes into the front of the intake.

The one under it is whay usually causes problems.
It wouldnt hurt to replace the o2 sensors either.
