I have a 97 5.2 and the check engine light came on, its says purge valve fault so i did some research and removed the purge solenoid. I read that if you shake the solenoid and a bunch of black granules fall out you need a new solenoid and canister. Well i shook my selenoid out and i had three little black granules come out. Does this mean I need a new selenoid and canister or not? Any help would be greatly appreciated! Thanks you.
