I experienced the same problem last night. I thought it was because I forgot to put engine oil in my car, so I did that today. Still had the problem. I then went to an inspection shop where I was told it could be a number pf problems. He said I should disconnect my battery terminal for a few minutes because the vehicle entered “limp mode", which prevents you from damaging your engine (or something in that regard). I disconnected it for about 5 minutes and my check engine light went out. Its like a code that you reset by restarting the battery beginning with your battery terminal. My vehicle is operating normally now and I feel so relieved that it could be fixed my something that simple. I was thinking I'd need a new catalytic converter after doing research. I hope this helps you all as well. It's worth a shot.
