    Question How do I change the AIR Control Valve & K134 Relay?

    Hi everyone,

    I recently bought a new K134 Relay, which doesn't sound too hard to change. But is there critical steps I must do before & after plugging this new one in?

    Also I have a brand new AIR Control Valve for the notorious P0411 Code. What must I do before and after replacing this?? Thanks in advanced!
