Car dies when grounding timing through link

[97gsexx]

I have a question regarding ignition timing. I dialed in my 1650cc injectors and at idle everything looks good except my timing varies from 7*-17* at idle. Before dialing in my injectors I verified that my ignition base timing was at 5* using a timing light. Now, when I attempt to check timing and check the ground timing box in link, the car dies.

When I start the car with the timing grounded, the car dies as soon as the front o2 cycles. I have read that it is normal for timing to bounce around during idle but 17* seems a little high. I have also read that the car should run rough when grounding timing through link, but not die.

Has anyone experienced this issue? Thanks in advance.
