I had an issue when sometimes my 2000 1.8L Corolla stalls if I roll in reverse. A few weeks later, I got a check engine code pointing to Bank 1 Sensor 1 as an issue. I replaced it, cleared the codes and thought it was cured.
A few weeks later, the light came back with a new set of codes pointing to the MAF sensor. Aside from a barely perceptible vibration at idle, it drove and continues to drive fine. I cleaned the MAF sensor and the check engine light disappeared. Again, I assumed the problem was cured.
Today, the check engine light comes back on with the same code. I am wondering whether there's a leak in the system. Perhaps, the 02 sensor isn't snug enough on the exhaust? I've included the freeze frame for the code, I also included MAF volume vs the 02 sensor response (long term) graph when tapping the gas while in park. The last images are two pages of sensor data while holding the RPM.
