Found 3 codes-P0053, P0300, P0442. For P0300-misfire codes, scan test and monitor cylinder misfires. #6 cylinder had the most. Perform engine compression test. #6-85. #3-120. #2,4-100. These are low and uneven and indicate a problem with valves. This GM engine has a history of valve issues.
For code P0053-Test and replace Bank 1 sensor 1 O2 sensor
For code P0442-clean fuel filler neck lip and replace fuel cap
