Re: [DML] Finding engine problem

[Warren Wallingford <warren@xxxxxxxxxx>]

If there is just one cause of all three problems, it will be a breach in 
the vacuum line from the engine to the brake booster.  I have heard of 
the hard line cracking.  It runs along the RH side of the car up against 
the frame.  It connects to the engine vacuum with a flexible hose from 
the RH intake plenum.  The booster also connects with a flexible hose up 
front.  See page 6-3-1 of the Parts Manual for the layout.
