Vacuum is solid at 17-18 during idle and when it does get started, it maintains 17-18 and goes slightly up if I ease on the throttle to rev it up. if I “burp” the throttle and the engine bogs, it goes down to around 5 or less.

So far the parts I have swapped have been listed as the same part number; with the exception of the oxygen sensor which due to it being pre-cat, I would think it would be the same since it is the same engine.

im not 100% about a vw but all my cars run a solid -20hg at idle
