I'm trying to eliminate as many parts as the cause of some issues I'm having and I'm testing the map sensor.

What's the default voltage for it with zero vacuum? With it outside of the cat I get around 2.77-2.78v. Creating a vacuum by sucking on it with my mouth shows a steady drop in voltage which means the map sensor should be good, if it's default is at the correct voltage.

I'm not sure if this is the correct sub forum for this so please move if not, thanks.
