OK, moving the distributor on that engine doesn't change timing. It changes injecter synch. In order to set it correctly, it requires the use of a class2 scan tool that has a PID for camshaft offset and it has to be adjusted to "0".

I can give you a procedure that will get it close enough to run but if you are off more than 3 or 4 degrees, it will put the check engine light on with a P1345 code.
