as others mentioned, it could be the maf sensors are dirty. ive not had issues on my cars (like *many* cars using kn drop ins
and cones) but they are notorious for causing oil to get onto the sensor.

as for the post-maf... im not sure. mine works fine and have been running it
for like 3yrs now with no issue. maybe your hose is loose or
elbow cracked or something as seen on those stillen gen3 intakes...?
