I would have to do testing to thoroughly check it out with my freeze frame oscilloscope oxygen sensor testing is very complex to do correctly and there are so many different variables so you're going to vacuum leak that's going to make the data weird so you got to find the vacuum leak first or it runs rich it'll also make the data weird and that would have to be checked out
