CEL issue

A while back i got my m235 and about a month after getting it i made the mistake of buying an injen intake. I constantly had a CEL for a running lean code. EVentually I upgraded the charge pipe, FMIC, VSRF catless downpipe, and spark plugs and went BM3 Stage 2 Agg. Fast forward to now, I have the stock airbox with an K&N intake filter and constantly get codes for running rich, running lean, and airmass too high. The car idles extremely rough and sometimes stalls when started (unless cold start) along with the car jerking between shifts when under load and it doesn't feel like it's running at full power. I tried cleaning my MAF sensor and it still acts up. I just ordered a new MAF but any ideas of what it could be?
