Hi Peter, I take it the inlet manifold gasket is ok? These were prone to leaking and there is a modified one,made of very thin steel, but normally you get a miss on a cylinder, they were also prone to the stepper motor sticking, giving either a fast or a slow idle speed, but you can usually see that the stepper motor is not moving as you open/close the throttle. If it is the stepper motor you can often give it a jolt from the car battery to make it work again but if you read any of the tech books they tell you not to do this, Jim.
