Rough idle and fluctuations

cleaned all of that already. I’ll update once I get some parts in and replaced.

 

I’m still dealing with the bullshit lol. I think I’ve found all the leaks and it’s these MFs on the exhaust system. I could hear it but couldn’t find it. I found 3 earlier and the big leak is after the upstream O2 sensor at the welds when I replaced a new catalytic converter. Craftsmanship is non existent and I failed to check the work after. I should ask about warranty with craftsmanship. These welds are boogered. Smh
