When I come to a stop light the motor wants to surge up and almost stalls
All vacuum lines are failing. all plastic lines are britle. starting to replace one by one. haveing trouble finding a good diagram to work off of.
while changig spark plugs, i had to move plastic vacuum line, and the plastic vacuum line where no longer flexable, they where very rigid and brittle, as a result they broke very easily.
