Has anyone experienced this before? I got my car tuned recently at Church automotive and it was explained to me that it could be a bad o2 sensor or maybe an exhaust leak.
Any ideas on how to fix this ?

You would need to do further diagnostics via logging and look at the afr readings of the front and rear 02 sensors and compare, with commanded AFR. also look for high LTFT.
If you have no devices to log ecu parameters then take it to a shop
Or just take a punt on the rear 02 being faulty
Code P013A indicates problem with rear 02 sensor, but it could be exhaust leak or cracked header, or a multitude of other issues
