Well, I finally finished putting new Head Gaskets, and exhaust sytem on my 89 Max. It started on first crank, no leaks, no over heating - just terrible idle. Runs great in driving range, but lopes at idle. Sounds to me like a vacuum leak. My tapes markers on the hose hook-ups fell off and I was "guessing at the correct hook-ups. I received the diagram for the vacuum hoses, but it almost impossible to interprete. Any ideas how to trouble shoot. Any pictures availble of hose hook-ups?
