Here is a link to the online manual. You say you have a GE so it starts there.
Ignition timing:

Make sure the airflow meter is plugged in and that the bundle of ground wires on the intake side under the intake manifold is tightened down.
I'm assuming you checked the valve clearance of each valve to be within specification.
