I know these northstar engines have a lot of problems as is but I don’t think it has to do with any oil things, but, I’m in the cold left my car running went in the store came back out and it was off. I turned it off as I was getting power just no motor function. I went thru the error codes and got these (IRC u1016 PCM po130 Po171 Po174 Po300 Po325 po455 Bo100)
