My '93 Eldo has 104,000 miles on it and I am doing a lot of routine maintenance on it at this point. Should I replace the little, high-temp green hose(s) as a preventative measure. Do they go bad?

Re: Little green hoses
I believe that is a silicone hose and is supposed to last a long time. I hope so because it looks like a bitch to get at. If the TB is off I'd replace it. If not, I wouldn't touch it til I absolutely had to.
I've learned on here those are high temperature silicone hoses.
Do not replace them with regular heater hose, even though they are expensive, compared to regular hose. Regular hose will fail quickly because they are located in places that have a lot of heat from the motor.
