You paid DeLorean One $12,000 for an engine rebuild 100 miles ago, and you are coming here to ask about "engine shaking" problems? There is no way in the world an engine rebuild should have cost that much, but if it did and you are having problems, the first place you need to be asking questions from is DeLorean One. And after spending that much, I would hope they would tell you how to adjust your shifter for free. If not, you need to seriously reconsider your choice of repair shops. I hope that was diplomatic enough to get by the moderators. Its not what I would like to have said..... Darryl Tinnerstet [Non-text portions of this message have been removed]
