alright i statred my car tonight to warm it up after work came out 10 mins later and it has a cel on drove it home and got a fault code 12 i know what that is i just changed my battery . code 31 EVAP solenoid circuit Evaporative purge solenoid / Clogged purge line / Vacuum hose / Evaporative emission canister clogged . wtf is that can any one tell me what that is

Won't hurt performance, it's just emissions related.

Do you have all your vacuum lines connected?

alright all my vac lines seem fine except the one on top of the tb its cracked a little htf do i get the cel off without a datalogger
as for emisssons i got alot of them i don't have a cat can that be fucking this up

There's another thread on here going right now about this same thing. You might want to check it out too.:P

Check engine light 31 is not related to your catalytic converter. Just unhook the battery for a couple of minutes and it will get rid off the check engine light as long as the vacuum line is hooked up and everything else related to EVAP is ok.

I got this check engine light once when I was working on my intake manifold. I simply forgot to connect the vacuum line back up - this is the vacuum line right on top of the throttle body. I hooked it up, disconnected the battery, and then started the car. The check engine light was gone.

Hope this helps,
Kurt

The line on top is the reason you're getting this code.. That's the line to the EVAP system. Fix it, and it'll go away.
