96 park avenue emission control parts

I am trying to find the folowing emission control parts on my 96 park avenue:evap canistor purge solenoid-evap vacuum switch-evap vent valve.These are the names of the parts from the service manual.I am getting a code p1441.I need gm part numbers or autozone or oreily or advance auto part numbers.Thanks

I would be leaning towards the purge valve......first thing, remove you engine cover, and look for a vermin nest....they like to eat vac lines and insulation on the wiring.....

P1441 means it sees purge flow......you have two lines on the purge valve....one line goes to the intake(vac source).....the other line on the purge valve goes to the tank......disconnect this line from the valve and attach a vac gage......disconnect harness to the valve/solenoid.....start car....if you get a vac reading with car running, you need a new solenoid/valve....
