I left my 812 for probably a year without using it. When I started it up again, I immediately had problems shifting into 1st or reverse when I was stationary. Eventually it worked after a big push on the accelerator, but similar problems occurred when I was driving and the gears stopped changing. At the same time, my engine was running too lean. So I'm thinking of a leak in the vacuum circuit. What do you think? Where should I check first?
