P1423 Bank 1 Air Flow Too Low
I've had a check engine light on for a while now and the code is P1423. I had it checked and was told to replace the passenger side O2 sensor and to check the vacuum lines. Well I had both replaced and I still have the light come back on. Any ideas what else might be causing this?
