When checking the timing at around 800 rpm on an autoxray 7000 it shows it at -23 to -25 degrees. Is there a way to properly adjust the timing with the scan tool. I guess I am an off a tooth or 2 on the distributor. With a scan tool can I move and recheck the timing? What should it read? 0 degrees? Do I have to rev the engine beyond a certian rpm to check? Perhaps checking the timing the traditional way would be better? Does this distributor lock in place or can I advance it by turning it some. I keep reading that some lock into position and some can be moved. Have not actually looked at what I have, just trying to get a good idea till I go out and start messing with it. The truck runs ok, has a bit of a hard time starting and recently failed emission due to HC. Any instructions would be great!
Thank you for your time,

Timing is not adjustable on it.
You can turn dist all day and not change timing.
Code 1345 is for camshaft reard setting out of specs/off.
To set camshaft retart you will need a engine capable scanner capable of reading cam shaft retard setting.
But First
Set dist with rotor to the no 6 on dist base with engine on TDC compression stroke.
Then start up and run engine and hook up scanner.
And read out camshaft retard.
Not timing advance reading.
The camshaft retard reading needs to be as close to - or + o degrees as you can get it.
Over 2-3 degress - or + can throw code.
Let us know how that goes.
