I wouldn't have noticed before, because I bought this car with a blown engine so had never seen it running.

I suppose the ecu was talking to the tank solenoid and incidentally activating/deactivating the vanos solenoid, and vice versa. I fixed the wire issue and the light went off and has stayed off. The car runs great now.

I went and had the state inspection passed yesterday, and registered it this morning. Hooray!
