Left bank receives minimal fuel. Exhaust manifold gets mildly warm. Right bank is fine. NOID check indicates electrical impulses are fine. Fuel pressure is fine..
Does anyone know if each bank feeds through its own orifice in the central injector?
Has anyone taken the central unit apart to see exactly how it works? Injector cleaner, Sea Foam and Lucas have been used. There was a short duration of all cylinders firing then the left bank shut down completely. It would be very unusual for all four cylinders on the same bank to stop working at the same time unless there is a common supply line.
