evap delete?
I've been having trouble with evap codes coming up and im tired of dealing with them. How simple would it be to just cap the system off and then delete the codes with a pcm tune

Well I also have been having some odd running issues where my rpms bounce under load analso when I first crank, im beginning to think its vacuum leak related and wanted to eliminate the evap as a possible source since its causing codes anyway

Eliminating evap will not fix your idling problems. There'* a reason why evap is there. The easiest way to deal with these kinds of problems is to have the system smoke tested. They'll hook it up to a smoke machine and find the leak. I would recommend that over deleting the entire system any day, if its even possible to delete the entire system.
If your car runs like crap and you have evap codes, its likely your evap purge valve. Its a ~$30 part and takes 5 minutes to replace.

I know this might sound like a dumb question, but have you replaced all of your vacuum lines?

Actually no most of the lines have not been changed, I am going to inspect them a little and see if I missed something that blatantly obvious

If you're suspecting a vacuum leak, get some carb cleaner and spray every part of the engine bay that might have a vacuum hose connected. If you notice your car idles differently or revs up a bit when you spray a particular spot, you've found your leak.

just went out and inspected/sprayed a little and didn't notice anything. lemme just recap all of my symptoms in case there'* a common thread I haven't seen,
1st I had P0452 and P0453 DTC'* one is fuel vapor sensor low and the other is fuel vapor sensor high, I figured the sensor was going bad and planned to eventually change it.
2nd the car started doing this bouncy RPMs thing when driving under small load (not enough to downshift)
3rd I started getting the check gas cap DIC message and I noticed that the inside of my fuel door is always extremely dirty
4th I get the codes read again and now I have pretty much every evap code in the book totaling about 7 or 8 some being doubles
and now here I sit with a stupid emissions problem in a state that never inspects it
