big issues with injectors with that motor. I would have them cleaned as they may be varnished up from sitting.

youll need to scope the engine to find witch cylinder it is.try removing the plug wires one at a time.when you remove the wire from the distibuter the engine will slow and pick back up when you reattach it.if the cylinder is bad theyll be no change in the engine.you will need to wear rubber gloves to do this.
