Replace the EVAP canister on top of the air box. It looks like a small film canister.

Thats the purge valve Nate

The canister is actually closer to the gas tank. The purge valve controls the flow of vapors into the engine to get burned. The canister collects them out of the fuel tank so they don't escape into the atmosphere.

So how do you know this is the problem with code P1137 (my problem also.. 97-A4-1.8T)? Other posts talk about the pre-cat O2 sensor and MAF sensors being the cause...

Please advise.
