misfire codes 71-74...what are some causes?
I'm getting these random codes on my B18b I just swapped in and I can't find the source. Car misfires (not so bad when warmed up). Just wondering if anyone has had experience with these and how they were solved.

I was thinking it may have something to do with the exhaust. I have a dented dc 4-2-1, stock b-pipe, and spoon axle back. There are alot of bottle-necks in the exhaust.
