Try disconnecting (unplugging) your O2 sensors one at a time and driving after each disconnection to see you get any improvement. One of your four O2 sensors might be screwing up the air-fuel mixture.

Hi Jerry, I have p0133 dtc so I cleared the code and unplugged it before my morning commute. Immediately I got a CEL code p0032, but no P0133. Tried the gas cap tightening but don’t think that’s it. Cleared the 32 and plugged the sensor back in. Now waiting for the P0133 to pop back up. Any suggestions?
