Hello im new to the Alfa world. I am working on a 1991 Alfa 164S. The engine was rebuilt by a local shop, than caught on fire in the engine valley around the fuel rail. The wiring for the fuel injectors was repaired and spark plug wires replaced. Now it has a miss. I have narrowed it down to cylinders #2 and #3. Where can i find wiring diagrams, firing order, any ideas? Thanks for the help.
