I've had my 68 coupe jacked up (rear only) for the last week. Last night, we took it back down and this morning I moved it back from the garage center to its parking side. When I moved it out last week I had no problems; however, this morning the car had no idle speed whatsoever. It's not a very comforting feeling to be trying to pull a car into a garage by trying to control the accelerator and not having it shoot forward through the wall. Any ideas as to why Murphy suddenly won't idle? I really don't need this problem now.
