I haven't had a chance to bring it to bring it to the dealer yet and won't be able to for another week or so because I'm leaving for vacation Tuesday. Please keep us posted, I'd love to know the resolution to this issue.
This is exactly what contaminated injectors and carbon buildup feel like. Shuddering at idle and stumbling idle are usually carbon buildup rather than injectors.
