Started thinking I felt a miss under a load a few weeks ago. It has gradually gotten worse and confirmed to me that there is a miss and full on stumbling at times. It's either intermittent or after the car warms up and it switches to closed loop. The code that it's throwing is Lean bank 2 code 44.

\Where should I go from here? I thought about unplugging the o2 to force it to stay in open loop (if it runs with no issues then I know it's the o2 I think).

Thanks in advance!

 

Engine just seized up.... nevermind
