p0449 is a EVAP code here is something to check had a few of these inspect the wiring harness coming out of the right rear floor pan area at connector The harness is located in front of the EVAP canister, and will usually show signs of wear. Make sure that you inspect all the wiring carefully and make all necessary repairs
hope this helps

you have to take out the gauges, they will be on the back. In some cases you have to take apart most of the dash to get the instrument panel out, sometimes you can just take the trim off the instrument panel. I had to take apart most of my dash in my 86.

The vent solenoid valve has been redesigned to correct the problem you are having. I would recommend purchasing the dealer component.
I am not aware of any aftermarket parts suppliers.
