So I have been doing some datalogging and tuning today and my right bank has weak spark and I am thinking it has to do with the coil pack grounds. I have looked everywhere online and can't seem to find where the grounds are at on the car and when I trace them back I lose it in a tangle mess of wires. So if anyone knows I would appreciate it a lot.
The coil packs are ground side triggered, so they technically ground through the PCM. Where the actual spark grounds through is through the block and to the cables on each side, one to the - battery terminal, the other to the passenger frame rail
