Did a quick pull, the run went good couple counts of knock, tuned the timing to get rid of the knock and turned down the fuel some as i was hitting ~10.0afr. Went back to my "closed road" and went 2.5-7k in 3rd and when i shifted to 4th i got 27counts of knock and the car sputtered bad so i let off. But i can go do 2nd, 3rd , and 4th gear pulls and no knock? Any thoughts?
Why i think its phantom knock, I have stiff motor mounts, balance shafts deleted, and a 6puck. heres a screen shot of the log where the "knock" happened
