Art,
Yes it's a wasted spark motor. The coils fire the injectors in pairs, one coil fires #s 1 and 4, the other coil fires 2 and 3. When I pulled the injectors individually, the engine ran the same. With 1 and 4 being the non-firing injectors. When I pulled 1 and 4 at the same time, the engine ran the same. I had new plugs in it at that time. stopped the engine, pulled the plugs, 2 and 3 had a tannish deposit, 1 and 4 were clean, they had not fired.
This isn't a fresh engine. IF we keep the car. I can pass this off as a learning experience. Right now, I just want to hear it run on 4 cylinders again.
