Hi, new to Acura's and new to this forum. Couldn't come up with an answer in the archives.

I have recently replaced all 3 o2 sensors on my car in an effort to get the check engine light off. I am still kicking a code: Oxygen sensor heater circuit bad, bank 1 sensor 2.

Anyone know how to know which o2 sensor that is?

I am also getting a code for the EGR, says the EGR flow is insuffecient. I cleaned the EGR and I am hoping that will help. Any tricks there?

179K on the clock... car runs great!

TIA
Greg
