    what year is your burb? your user name suggests 94 but your profile says 97...
    you only need a socket / ratchet & timing light.
    but if you dont disconnect the timing relay wire ( thin tan/ brown wire under glove box)
    then you'll never get it set right.
    this has been covered before in other posts for your vehicle.....

    You need a scantool that can display the CAM RETARD value. I have a couple scanners and I have HP tuners - none of them display CR.
    So when I was curious, I flipped $25 to a gentleman (friend) during lunch to put a GM Tech II on my truck and read CR. It was on 3. We adjusted it to "0". Spec is 0, +/- 2.

    I don't know of any inexpensive or free scanners that can read CR - only the expensive ones, which is why they want $$$$$ to plug in. I suggest the weasle method to get it checked if you need to check it. As a general rule - if the truck runs and doesn't set codes - you're in the right range.
