Various drivability problems can be caused by vacuum leaks. This engine has plastic tubes that become brittle and crack over time. These tubes can be replaced by normal vacuum hose but be careful when changing the Tee fittings or hose connectors because some have built in restrictor orifices (usually color coded). If the restrictions are missing, drivability problems will most likely result.
