Bummer was hoping it would be an easy fix. Next would be to test the O2 sensor to make sure its reading accurately. Or you can just replace it with a new one. There's quality replacements for not much money. I'd test to make sure that's the case first. I'd also recommend a smoke test of your airbox and intake system to rule out any leaks.
