Hello I recently purchased a 92 325i with a m52b28 swapped into it with m50 manifold an 3.5 MAF and injectors.
Failed smog @ 15mph by 200 points on the nox.. I will try to post pics
Po, who is on these forums may see this, got it to pass smog by 5 points. 780 out of a max 785.
A year and a half later it's at 1000 and 950
I'm wondering if you guys think there is a vacuum leak or it's running lean or if I should just use a bottle of heet, change oil, and make sure I get it warmed up better?
Thank you.
