Evap

what can i do to get rid of it?
i'm throwing a code right now for it PO441 or something like that

i've heard i can get rid of everything down to where it comes out of the fender and block it off at that point and then drill a small 1/16" hole into the gas cap to compensate....

any other ways to go about this?

P0441 Evaporative Emissions (EVAP) system no flow (during purge)

Could be a simple case of the line being plugged with carbon, the solenoid plugged, or sticking closed, a leak in the vacuum line from the TB to the purge solenoid or a faulty flow sensor switch. Fixing it wouldn't be a bad idea. You will get a lot of fuel smell in the back around the fuel tank without the purge system.
