Ruff Idle 04/S4
 

Got Codes
P0300 Random Misfire
P0304/05/08 Cylinder Misfire
P0153, 02 sensor
This is a 04 s4 w/ 48k on it, well takein care of, just started idleing ruff couple days of go and now runs like sh%t. anybody have the same experience?? glad its under warranty...it will have to take a trip to the dealer i'm sure.

RE: Ruff Idle 04/S4
 

from those codes it sounds like the O2 sensor is misreading and bucketting in fuel? This in turn is flooding cylinder/s and making it misfire?

Could be wrong, please let me know what they reckon it is.

Thanks

Get it to the dealer before you reach 50K mi.
