Timing on a 91 Grand Am

How do I adjust the timing on a 91 Grand Am with the Quad four engine? It has the coil pack instead of the distributor. Any help is appreciated. You can reach me at snipped-for-privacy@neo.rr.com
        Thanks,         Gary

You can't. It's completely controlled by the computer. GW

There is no adjustment. If the timing is off, something is broken.
