I have a 2000 Tundra. I have replaced the ignition coils before but this one confuses me. Engine is missing pretty good, especially when motor kicks into overdrive. I have the following codes:

P1305: Igniter Circuit Bank 2
P1310: Igniter Circuit Bank 3
P1320: Igniter Circuit Malfunction Bank 5
P1340: Igniter Circuit Malfunction Bank 8
P0308: Cylinder 8 Misfire Detected.

Previously I would get the P030 codes and would replace the coil. I have cleared all codes once and it has thrown the same codes again. However, I don't know what to make of ALL these codes. Anyone provide any direction? Thanks in advance
