Hi
I had the red triangle and engine check light on my 2004 Prius and was getting a 3191 on my OBD. The car seemed to be running fine. I cleaned the MAF sensor and surrounding area put it back together and there was no triangle or engine check light. However when I plug in my OBD 2 it still shows a P3191 code. Car seems to be running fine? What should I do next to try and get rid of this?
