It went into limp mode and initially gave me a misfire timing trouble code. I swapped the spark plugs and coil packs and cam shaft position sensor and cleared the codes. The 0012 came back.
The timing chain has been replaced. As well as the guide and tensioner.
I reached back out to the builder (hour and a half away from me). He said it’s likely the balance shaft delete causing an occasional knock.
Not finding any threads or google searches for a repair shop in Oklahoma City area.
Any recommendations I’m missing? OKC or Edmond?
it’s built and tuned but a bit over my head for timing adjustment. Three local shops turned me away!
