2002 Camaro V6, p0174 with a check eng light.

Question

I've got a 2002 Camaro, 3.8l V6.
I've changed the intake gaskets, EGR valve, PCV valve/gasket.
New catalytic converter and O2 sensors.

What's next? fuel injectors?

Any assistance is greatly appreciated.

Answer 1

P0174 Fuel trim too lean Bank 2

Leak down test would be the best route to go, the reason this type of engine the cylinder head can be seeping coolant into one of the cylinder creating a lean condition. note any coolant loss.
