Hey guys,
a few days ago received my Ross Tech cable, and did a Auto scan under engine. I am getting random misfire codes, see code, also getting a O2 sensor code. I just replaced the O2 sensor the right side Upstream. however I was told that that code means I need a new catalytic converter?
secondly what could be causing the random misfire? I drive car daily and the car runs very smooth,and has plenty of power, it does not feel like a random misfire on all 6 cylinders. I have had a misfire on my other car on just 1 cylinder and i felt the engine shake, and lost of power. This is not the case with my Audi. the engine does not shake, idle very smooth, and accelerates as it should .
