Resident Street Racer
well, on my other log, i was getting like 20+ counts of knock. found out my knock sensor was trashed. so i replaced it. car pulls MUCH better now. it actually pulls again in 2nd gear. but in third, it starts to knock again. it goes up to like 20 counts. why? my high fuel trim was 116% before i changed the knock sensor and now its around 103-6%. mid is 100% and low hovers around 90-105%. btw, this is a 90, fuel trims range from 80-120 if im not mistaken. why is it still knocking? i have 93 octane. will rewiring the fuel pump help any? btw, i haven't changed the fuel filter yet. another note, i went to emmissions, and my co2's were offf the charts. the standard is like .80 my cars reading was 7.80 or something, better then last time, it was like 15.6, what does this mean? my mas is not hacked or anything. currently im running stock boost, and have a cat on. i will post any additional information as needed. thanks.
