Answer
David,

The vacuum cut valve is located on the intake.  Buy the new one and you can see it when you open the hood.  I think the only tools required are a ten millimeter wrench and a pair of plyers.  Disconnect the battery for a frew minutes to reset the code.  Before you take it in for the smog check drive it few times to get the computer out of learning mode.  Basically, drive it onto the highway and back to the house and turn the engine off.  Do this three times and the car will be out of learning mode.  If you take the car in for inspection before this the computer will tell on you that the computer was reset recently and you will not pass the smog check.
