I took it to a shop they claim they fix it but I rode about 1/8 of a mile and the plug blew again truck is now sitting still for a year and im ready to get it fix brought a kit not sure if its right but I need some help can some tell me where to take my truck so I can have it fix

 

You can ask a dealership if there is a shop they would recommend or have the dealer do it.
