A bad MAF will cause this too. See if you can read airflow on a scanner. Check your OBD fuse otherwise it said it "wasn't ready" because you had just previously erased the code. The scanning of the sensors resets after x many miles and x many startups. Don't erase them until you know what they are. They will lead you to the problem.
Edit: You could also be in limp mode and have a bad positioning sensor. Here is another same issue but was MAF. https://my.is/forums/f115/2001-wont-r...-reset-422425/
Need codes plz.
