Cold natured and boost gage

[drdave69]

Went to drive my GN in 35 degree weather and let it warm up a little but was not enough. Stalled/shut off when backing out of the garage. Also did it when leaving from my destination after completely cooling off. Had to sit for quite awhile to get it to operating temp before I could drive. Where do I need to look for this symptom?

I also noticed on this drive that the boost gage isn’t working at all. I checked as many vacuum lines as I could find with no obvious problem. My car has the GNX style gages in it but I have not checked the actual gage yet. Any clue to what to look at for this?

Does the boost gauge read from the MAP sensor on a GNX style cluster? I'm pretty sure it does on GN clusters.

What degree thermostat do you have in it?

I believe it to be a 160 thermostat. The GNX style cluster was already in the car when I bought it a few months ago so I don’t know what feeds it.

Sounds like vacuum leak / boost line off. Zip tie it and all the rest. Magic secret of all TR guys.
