unfotunatly to set it you need the right tools, easier to take it to a mechanic. Maybe a new cat. This is what I put in my car and helped a lot for the idiling, real easy to install, just connect to the battery, trust me its good, it works for me.

Dont worry there all universal dont pay attention to the name
