The car drives fine but at a long stoplight, after 1.5 to 2 minutes, it will shut off as if the key was turned off. If I put it in neutral and rev it, it will hang at 1500+ rpm for a while before settling down to about 1100. I ran the codes. KOEO shows 181 and 556. KOER only showed 116, so I may not have warmed it up enough. I'll do the KOER again after picking up my wife tonight. Different sites said:
181 - Fuel system was lean at part throttle Single, Right or Rear HO2S – Fuel control.
or
181 - Fuel system at rich adaptive limit at part throttle, system lean.
556 - Fuel pump relay primary circuit fault – Power / Fuel Pump Circuits.
or
556 - Fuel Pump Relay primary circuit failure.
Any suggestions on what to do next?
