    i am really interested in this info i haven't had mine to the shop yet and i'm wondering if i could time mine myself without using the shop scan tool. if i just set mine on tdc and then put the number one plug in line would that be what they did or was it diff than that because the computer would understand what has happened and react accordingly if i got it right should just be fine if not throw code and i put it back what do you guys think?????
