My engine light keep coming on the code is po446ichange the purge vale and something said it might be the intake manifold my truck is 2006 canyon truck
This code has nothing to do with the purge valve . Evap vent valve . Has nothing to do with intake manifold.
An intermittent condition could be caused by a damaged EVAP vent housing, a temporary blockage at the EVAP canister vent solenoid valve inlet, or a pinched vent hose. A blockage in the vent system will also cause a poor fuel fill problem.
• An EVAP canister, vent hose or vent solenoid valve that has restricted flow may cause this DTC to set. Using purge solenoid valve command with a scan tool will allow vacuum to be applied to the system instead of pressure. With the EVAP canister vent solenoid valve open and the EVAP canister purge solenoid valve commanded to 100 percent, vacuum should not increase to more than 9 inches H2O.
Your best bet , take it to a qualified repair shop.
