ok so i just got my car about a week and a half ago and the car is so nice. the only problem is that now its not running as nice as it did when i got it. its pulling alot softer in first than it did a few days ago. car was running and pulling fine up until it threw a CEL for the knock sensor. but than it went away and hasnt come back but the car is still running crappy.
the pull in first gear is slower. the car's rpms rev up high but the car dosnt have as much "ufff" as it did. in the later gears the car pull a little better but not 100%.
also i noticed that when i was going about 60-65ish on the highway that the turbo would wine in and out louder than the normal turbo sound.
well thats my problem, any ideas?
