What is this? Still trying to find the problem.

Rod,
If you want to try a 3rd, I have one off an 83 which should be the same. BTW have you checked the thermotime switch to see if it is cutting off after a few seconds? Also, on the 83 AAV mount and water outlet there is a vacuum advance temp sensor. If yours has one, does it restrict the vacuum when cold?

I don't know about the vacuum advance temp sensor. Is this the temp II sensor? I've replaced that with a new one, but that may not be what you're referring to. It's obvious that you know a lot more about this than I do, so please bear with me.

Rod,
Not sure about your 82 but on the 83 that I got the AAV from, there is a vacuum temp switch that reduces the amount of advance vacuum until the water temp is up. I can't find it in a schematic but it is commonly used L jet and later Bosch fel injection systems.

Just replaced the TSZ switch unit, no change.
POOP!!
Thanks

Rod,
This isn't the best picture but for the moment it is all I have (grandaughter has the good camera). The temp switch is the black object at the lower front of the coolant return/mount. BTW one of the connectors are broken off the switch.

My 81 stopped using that temp switch when I removed the air pump & everything with it.

My EEC valve is long gone - vacuum advance is plugged into the TB where its supposed to be.

I have one of these sensors (no. 29 in the parts manual, "thermo valve") and it connects to the throttle body AND has a broken connector on the other side as well. It was on the bottom and not visible when I replaced the vacuum lines. Do you know what it is supposed to connect to? It holds vacuum, but is obviously a temp switch that allows passage of air. but from where to the throttle body?
I applied heat and ice to it and it appears to only open when it is "VERY" cold.
Room temperature and it's closed solid as a rock.

Rod,
Is yours still connected to the throttlebody? If yes, I would plug the ports so it won't leak when the engine is warm. It appears to go to the fuel vapor cannister so it wouldn't affect your timing.

Sorry, "yes" it is connected to the throttle body with a T connector on one of the small vacuum lines. I guess I could plug it, but it sure seems tight now.

Next up, what is the switch in the vacuum line that is attached to the cross member and has two power lines to it? I've been through the parts manual and haven't found it yet. Can you save me some time? Porken, Dennis, anyone?
Need a photo? I can do photos.
