Are you using the timing gun correctly? Make sure you hook your timing light to the 'line loop' connection from the coils (usually in back). Look in the FSM! They have a good step by step procedure. If your using aftermarket coils like I am then you'll have to use a high tension wire between the first spark plug and coil in order to adjust the timing properly, its also shown in the FSM.

When you took your CAS off don't assume that when you put/punch it back in (dots line up etc) that it will be at factory setting and walk away (wrong). Other factors play into this ie, cams, thickness of headgasket and so on. Hope that helps.
