Hi there. It is possible that an EGR valve problem could cause the fuel system to run rich, but typically not cause fuel to leak. This is most likely a throttle body component failure, a fuel line leak or a fuel injector that is always active. It might be a good idea to have a professional mobile mechanic complete a fuel system inspection to determine what is causing this problem.
