Engine light warning PO161.PO441,PO446 Help!

Hi last week I posted that i had trimmer oil mixed with my gas and my engine light went on.I was told to get the codes. After I got the the scan and the light was turned off. It came back on again. Do I need to take the car into the dealer?Thanks for all your help!

I don’t think the trimmer mix oil has anything to do with the codes, but you should take it in.
