Two problems related to gas recirculation valve (egr valve) have been reported for the 1997 Plymouth Neon. The most recently reported issues are listed below.
While traveling at 10-15 mph consumer pushed on brakes and there were no power brakes. Took to mechanic, and they said it might be the check valve, and they replaced it. Then it happened again, second time they changed brakes, and it happened again. An independent mechanic found information regarding a memo that egr vavle would correct problem because water got in it and froze up causing a loss of power brakes. Chrysler is denying any knowledge of problem.
Consumer states that vehicle exhibited an oil leak at the camshaft sensor beginning at 35,108 miles. The leak continued to 05/30/03, with numerous repair attempts by the dealer. Consumer believes that the egr valve is cause of problem. The egr valva can not withstand the internal combustion heat in an illuminum block engine.
