Help 2000 Toyota Tundra Obd Codes

The Truck Runs Bad.. The Codes Are 1305, 1310, 1320, And 1340.. I Put New Plugs In And It Still Runs Bad. What Can I Do To Cure This? And What Does These Codes Mean?

You have an issue with one of these:

Coil packs
Coil pack harness
ECU.

I would start by swapping some coil packs around to different cylinders to see of the codes change.

P1305 Igniter Circuit Fault (Bank #2)
P1310 Igniter Circuit Fault (Bank #3)
P1320 Igniter Circuit Fault (Bank #5)
P1340 Igniter Circuit Fault (Bank #8)

Unplugging the injectors will not do anything. Your ECU is detecting a coil pack/ignition problem.

You will have to swap the coil packs listed above around to different cylinders that are not mentioned above. You will then have to reset the codes and then see if they come back. If the codes come back for those new cylinders, then those coil packs are bad. If the codes stay the same after switching, the wire harness is bad, or the ECU is bad. Either way, it's going to be expensive.
