I have a error code, P0357- Ignition coil G Primary/Secondary circuit malfunction on my 99 GT with the 4.6. It occured on a dyno run. I had just installed new Summit coils. The dyno guys said the Summit coils suck and thats the problem. My question is which cylinder is it and should I replace all the coils with better units? Does anyone have a list which identifies on a 99 GT which coil is which letter? I read somewhere that the G coil was the second from the back on the drivers side.
Any help or advice is welcome!
Thanks,
Ben
