Hi, my name is ***** ***** timing is set using a scanner to watch the cam retard, it must be set to o degrees on these or it will set this cod, do you have a scanner to set this?
Customer: replied 2 years ago.

no scanner just code reader and timing light

Expert:  Tim Mohr replied 2 years ago.
a timing light will not work on these, you need a scanner, the cam retard has to be set to 0 degrees, and a scanner is the only way to do this, there are no timing marks on these,Tim
