Hello Ron,I am not able to view the pdf file. We do have access to most TSBs, can you specify which one are you referring to. We have not done a complete diagnosis besides full scan all Modules, checked plugs and done visual inspection. I have an idea based on the symptoms, but appreciate your feedback.Thanks,MBR Team
