Last time I checked, at idle it was pulling about 18-19" Haven't tried seeing what it does while driving though, might be a good idea, thanks.

is the needle steady? you say 18 to 19", but at what idle rpm?
I agree with the suggestion to look for an exhaust leak, that could be a source of the popping noise.
