I have a 97 Neon. The Canister Purge Valve circuit gives a code 31 stating that it has a problem. I've replaced the valve, which didn't make the code go away. I removed the battery for a few hours, and the code went away. I drove for about 2 weeks and the code came back on. If it's not the valve, where do I look next?

It's called the Canister purge valve (although it's a valve and solenoid in one package) and it's purpose is to control the flow of exhaust gas from the charcoal canister to the intake manifold.

Could you describe this "canister purge valve"? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.
