2006 Chevrolet Suburban 1500 Z71 5.3L MIL Lamp on
This Suburban runs great but after 20 miles the check
engine light will come back with P0172 and P0175 Fuel Trim
Rich both banks. Originally it had an EVAP vent circuit
fault but since the purge and vent soleniods were replaced
the P0449 has not returned.
