Last week my check engine light came on and the truck was driving a little funny. At light throttle around town it was sort of hesitating, weird to describe but almost felt like it would if it were sputtering. You can hear and feel it running funny. Engine light came on, went to advance auto

Gave a code for bad o2 sensor bank 1 sensor 1(P0133) . Ordered the oem replacement, light went out in the meantime, still was running the same so I replaced it when it got here. Didn't fix the issue.

If I get on the gas at all it runs completely normal and no issues.

Any thoughts? I also put a bottle of Lucas fuel injector cleaner through it but no luck.

Maybe check the throttle body for build up around the inside. I know you say intake was cleaned so maybe you did it then but it could be acting up. Are you sure it’s engine related and not transmission? Just throwing out some ideas.

So I realized I ran into this issue before and was able to fix it. I Uninstalled the hemi fever tune with the Diablo, reinstalled it, truck runs perfectly fine. Happened to me like two years ago and fixed it the same way
