Mark, Answers below..


there is a coolant Y pipe 102147 under the intake manifold that has these 
parts in it
102478 lambda sensor and 102405 therm vac switch. since i will be in this 
area how do i know if these two parts are bad (102478 and 102405)? what do 
they do? should i replace.

( If the car is running properly, then I wouldn't replace sensors But, I 
would take them out and clean the exposed ends to the water and use Teflon 
tape to replace them.) 

Also the thermotime switch 102125 what does it do? should i also replace this 
too?

( Since the thermal time switch doesn't go out very often, then I would do 
the same thing. Clean the exposed ends and re use.) 
thank you
Mark, One other thing I would do. I would replace the green air vac switch in 
the internal water pipe. It's the one on the left side of the internal water 
pipe. Being that it is mechanical, if it doesn't move internally to re direct 
the vacuum, you could have advance problems. It's a moving part where the 
others are not.
