I purchased this van with an existing engine miss issue which progrssively got worse in cold or wet weather. The previous owner had the cap & rotor replaced during a $500 tune up. Local shop could not find anything wrong with the distributor cap or rotor so they cleaned and lubed it. Eventually with heavy humid conditions the van failed to start and had to be towed. Took it to a reputable Auto Tech here. They replaced the cap & rotor with brand name parts as these motors are very sensitive to moisture. Close to 2 years now, never had an issue again.
