Re: Techs and mechanics...codes on a camaro??
I would address p1406, and p1441 first, as they are most likely causing p0174. sounds like the EGR valve pintle is stuck due to possible carbon build up, remove the EGR and look for carbon, around the needle pintle. then I would check all the hoses going to EVAP canister for damage or disconnects, also check for a faulty gas cap, if the tank does not pressurize it will throw a 1441 code.
catalyst system efficiency below threshold bank 1 -
p1406 egr valve pintle position circuit
p1441 evap system flow during purge
p0174 system too lean bank 2
