Pops from exhaust

I suspect you have an exhaust leak.

Basically this popping is caused by fuel igniting in the exhaust. The added air will cause it to ignite rather than the hydrocarbons reacting with the converter.

The other possible cause is the vehicle is running rich. You can inspect the o2 sensor data with a scan tool to see if it is negative. If the fuel trims are negative that means there is less oxygen in the exhaust due to the higher fuel content.

However, I would start with looking for exhaust leaks.

Bank 1 is running lean.

Okay. I attached the testing for this code. They have you focus on a vacuum leak but as I said before the fact that you have a popping as well, I suspect the leak is in the exhaust which is allowing the air in before the o2 sensors which is leaning out the exhaust and it is causing it to ignite.

If we find and fix the cause of this issue, I am sure your popping will stop.

Here are some guides that will help answer any questions but let us know if you have any more. Thanks
