      I have a 2015 Chevy Traverse with 154,000 miles on it. I got a p0138 code last year and bought a walker brand 02 sensor to replace it. Couldn’t get the old o2 sensor undone so had Chevy do it. I’ve been experiencing shuddering/bucking while driving or accelerating. Since last month every now and then the traction control turns off and service stabiltrak comes on and engine power is reduced to 25mph. I switched out the throttle body and sensor and put a new air filter in. My spark plugs got replaced last April. Since replacing the throttle body and air filter I had the engine power reduced thing happen, except this time it didn’t reduce down to 25 mph. I have a CEL that will turn off sometimes, but it’s the same o2 sensor coming up. Bank 1 sensor 2. I have a code reader and I get p0138 and p013a. Autozone’s reader only shows p0138. I’m wondering if maybe it’s my MAF sensor or something else.

      You bought a non GM 02 sensor and that could be part on the problem or there could be a problem with the PCM
