1992-1994 Opti-Spark Distributor Unit ACDelco
The 1992-1994 Opti-Spark Distributor fails most frequently when exposed to moisture causing a no start condition, engine misfire, and even just generally poor performance. Direct exposure to coolant leaks from the water pump are a primary cause of failures. Due to the nature of the replacement work, it is wise to replace opti-spark distributor and water pump as a set.
