whats up everyone?

recently my car has started running like ****. There is massive hesitation in the car AFTER it warms up. I can barely keep the thing running when i stop at a light. SES light was on and both o2's were bad, and i have a #8 cylinder missfire. I probably cracked the plug when i changed them- I got the o2's replaced and bank 1 is still bad. WTF? Is it possible the o2 sensor was bad?
I have longtubes and an off road y-

Whats the reason for hesitaion? the o2 or the missfire. I can barely drive this thing and its my DD- thanks for the help!!

A4/M6? You should of tackled the spark problem before changing the 02's IMO because sometimes a heavy misfire like that can foul them out again. Check your plug wires, fix the misfire then I would clear the code and see if it returns.

EDIT - Is your SES light blinking? What codes are stored?

its a m6; not blinking but when the codes were read bank one was still bad and had a #8 missfire; i just cant drive the car man, it barely wants to idle. No response in the gas pedal either.

Something is definitely up with that #8 plug, wire - something. Sometimes if you pop the hood in the dark you can actually see the spark arcing. It is also very possible you could of cracked that plug, try swapping it out with another one.

ok ill check it out- and of course #8 is the worst one to change! just my luck.

could the o2 be the culprit to my shitty idle probs & hesitation as well?

Definitely get that plug fixed man. That sounds like your issue.

The 02 can definitely cause a headache all in itself, rough idle, running rich - lean, terrible fuel economy. That coupled with the bad misfire can pretty much make the car impossible to drive, especially when put under load.
