My car is doing is funny things lately. At around 3k-5k rpm it feels like the car studders a little. So I decided to do some logs to see if its out of tune. Look below. Right around the time I feel the car studder, timing is low. I wonder if what ever causes the studder is causing the low timing or is the low timing causing the studder. hmmmm. Other then the studder, the log looks good so I'm confused.
