My LT1 is suddenly running awful after getting my AC recharged. I also just cleaned and oiled my air filter, and did the oil filter adapter seals but even with the ac off it still runs like garbage so im ruling the AC out. The adapter seals also makes no sense to cause a mis. I did spray all around the engine with brake cleaner last night to clean up the mess I made with AC compressor oil/dye. Maybe I ruined something by doing this? It was mostly on the passenger side though and the driver side its where the misfire is.
Here are some videos of the idle:

Seems to only be on the driver side. Exhaust sputters and is not smooth. The exhaust is also dark and smokey on driver side. Strangely if I unplug one of the driver side spark plug wires I don't notice any change in idle. I tried all 4 on the driver side with the same result for each one, no noticeable change in idle.
Today on the way to get my AC system charged it seemed to run fine. It wasnt until about halfway home that it started to act up. Im hoping its the oxygen sensor connection since I had an issue with this after the filter adapter swap. Also the knock sensor wiring somehow became stripped, so hopefully it's just shorting on something? I noticed this after I removed that metallic like tape during the oil filter adapter gasket swap since it was all about peeled off anyways and totally soaked in oil.
The check engine light is off for now.
At idle the driver side exhaust has a periodic (but not on a perfect cycle) sputter as seen in the videos. Under throttle in park it sounds normalish. Under heavy throttle in gear it nearly bogs out and has awful acceleration and sounds terrible. Under light throttle its a total dog, sputters pretty bad, and bogs and I can feel some surging.
Before I did the AC, oil filter adapter, and air filter, I recently (<500 miles) replaced the opti, I was getting code 36 and 42, which vanished after the opti swap. I used a cheapo amazon unit with 3 year warranty. Maybe it's dieing? It is super hot (nearly 100 F) today. I installed an MSD cap and rotor and applied RTV to all the seams and blue locktite to everything. I also did the opti and water pump seals in the timing cover, water pump, plugs, and wires at the same time. I used 10.5mm Busidin silicone wires off amazon and double platinum bosch plugs. It was running great after these repairs/swaps.
Any ideas?
Thanks, Mark
