Well, the plot thickens... turns out I have a vacuum leak again! lol didn't think that could happen with negative fuel trims.... anyways, figured I'd post a really quick video of me doing the smoke test and where it's leaking from. I'll definitely be going with a new throttle body. This one is just too warped. Definitely just using rtv and no gasket this time though.
Good news is I used the same method on my exhaust and there are no leaks! (finally)
Still have to take out the o2 spacer. Still not sure how that works, but maybe it'll help. Looks like I have my weekend cut out for me...
