I have had this issue for the past 3 weeks since buying this car from a used dealer. They were able to tell me what it was and lowered the price because of the constant check engine light staying on. It was a northern vehicle for so time by the under body rust but the cars integrity is fine but the exhaust was nearly gone. I have retained the original catalytic converter but replaced both O2 sensors, EGR valve and put a NEW exhaust manifold as it was cracked but the OBDII still reads Insufficant Recurculation Flow, Bank 1 O2 sensor, and EGR valve. Im thinking that the catalytic converter needs to be cut-off and replaced. PLEASE SOMEONE GIVE INPUT
