Engine vacuum leaks on Dodge Spirit R/T

Problem Description and Possible Solution

Engines may develop driveability issues and illuminate the Check Engine Light due to engine vacuum leaks. These vehicles use plastic vacuum lines which can become brittle due to heat and age. Care should be taken when replacing these lines as some may have a restrictor orifice molded inside. If lines are replaced without including the restrictors driveability issues will remain.
