The car was having a problem before I even started working on it. So either I have a sensor gone bad or engine failure. Its idling perfectly fine. I flat out dont get it

It doesn’t matter if someone is stock or on ECUTEK; if you disconnect the negative battery terminal then the ECU is reset and needs to learn again, so the experience will feel less responsive and sharp, but especially your first time driving the car, it will feel like there is a power problem when aggressively on the accelerator as if the traction control is partially activating or timing is being conserved. You should have noticed this to some extent during ECUTEK reflashes as well.
The question is what caused the misfire in the first place? Fuel, spark? Did you look at the plugs and notice aging or damage when you replaced them, especially on the cylinder that was misfiring? You had a CEL with the misfires, but now the car drives worse, yet you have no knew codes. Isn’t that odd?
Also, there are people on original plugs with double your miles and stock plugs with three to four times the stock power, so my feeling is that the plugs were fine and the new ones might not be the problem. Maybe this is a fueling issue. I don’t know. What is your fueling setup? I could be wrong. Just seems odd.
