Thought I would make a quick post about replacing one of my 02 sensors
My power delivery was a bit rough and when idling the engine would rock almost like a misfire and the engine sounded rougher than my brothers does After scanning my car with ISTA I had 2 codes for the pre cat 02 sensor - 287500 and 287100 both relating to the pre cat 02 sensor After clearing the codes a few times they kept coming back. I used one of the functions in ISTA to test it and it revs your engine a bit and shows you a few fancy graphs and basically confirmed it was faulty I replaced it quite easily after cutting my hands to bits haha. After replacing it I cleared all the adaptations using ISTA because it tells you to do so Now the car doesn’t shake when idling and the power delivery is also 1000 times smoother. If you have the same issue maybe this post will help you. I couldn’t find anything about this so thought I would share my experience 🫡 |

N57s don't normally suffer from cylinder wall scoring though unless an injector has failed and bore washed it for 1000s of miles. See if your indy can do a leakdown test for you. |
