Well I checked the four bolts that secure the throttle body and while not 'loose' per se they did take a litlle torquing but were not loose enough to leakOne thing that keeps popping up in my head is throttle body spacer?
How much vacuum does it have at idle before it warms up? At the altitude where you are it should be around 17-18" Hg at idle.Ok I may be 'on' to something with this. Cleaned the 02 sensor connections and still runs the same HOWEVER I finally connected a vacuum guage. OK starts and runs smooth and holds vacuum BUT as soon as it warms up it starts 'stumbling' and the vacuum drops dramatically and the needle starts to 'fluctuate' with the running of the engine. Lets say its more of a rough idle than a stumble but it definitely changed when warm and the vacuum drops. All ideas will be considered!
Well my vacuum gauge was most likely used to test the first Model T off the Ford assembly line and its accuracy is in question but it was showing about 15 " but it was steady. No must have missed that post - please restate the procedureDid you ever try the Carb Cleaner trick?
Spray some carb cleaner around the base of the throttle body with the engine warmed up and idling.Well my vacuum gauge was most likely used to test the first Model T off the Ford assembly line and its accuracy is in question but it was showing about 15 " but it was steady.

If the idle speeds up and/or smooths out when you do that, the base/mounting gasket under the throttle body is leaking.
But the carb cleaner has to be the flammable type. It doesn't work with non-flammable.
Fortunately VERY accessible on the Cherocar - and a good idea - I'll do the rear next.Not the most accessible components to get to w/o a car-lift!
