I have a 92 6 speed. Came with no motor, Found 92 auto motor and installed, New Cats, new exhaust. Started and died immediately. Would stay running if the pedal was tapped/ feathered and revved, but no idle. Checked injectors, One did not ohm out. Changed injectors. Scanned with Genysis ODB II scanner. Suspect code 16 Optispark suspect. Removed. Has bad bearings and corroded contacts. Replaced. Still exactly the same problem. Checked grounds and plug connections. Any help or suggestions would be greatly appreciated.

Have you checked fuel pressure? It sounds like you have the spark figured out. If you have good fuel pressure, you may need to datalog to get something for everyone to look at. The first values I would look at are the MAP, MAT and IAC readings.
