Does this sound like a misfire to you??

e92life · 03-11-2017, 07:55 PM

I'm getting a cylinder 2 and 3 misfire and a 2C3A oxygen sensor code on my N54 335i. I'm also hearing a weird noise. You'll hear it the background try and ignore the injector ticking sounds.

Ticking of injectors is normal. Did you check your belts? Kind of sounds like the sound I get in my car mine only happens when i'm driving, not on idle.

I you are getting an O2 code your misfires are related to the O2 issue.
You have a bad O2 sensor.
