I know that the vent tube that runs from the canister to the top of the fuel tank is off....I want to know is it hurting me any or do I need to find out a way to put this back on....

anyone?

 

When the PCM opens the EEC purge solenoid, it is going to be sucking pure air into the intake, rather than the fuel vapor/air mix that will come out of a correctly functioning EEC system. The PCM should be able to compensate for that, using the long term fuel corrections (BLM's). But a vacuum leak - which is equivalent to what you have with the EEC canister not connected to the tank - hurts you some, because it drives the BLM's above 128, and when you go WOT, the PCM uses those higher values for fuel calculations, runs richer. Probably not a big error, but it should be fixed, or the line plugged temporarily.
