Well to make it short I've gone through the entire Evap system for a P0455 with a hard to refuel issue on my 02 xj8, replaced purge valve which addressed my hard to refuel issue. Soon after my purge valve begun making a trumpet sound a minute at a time every so often while driving or at a light. Car runs normal,normal fuel consumption and seems to behave normal asides the fact I sound like the titanic approaching a stop light and the MIL is on. Any advice appreciated
