Default Lots of codes!

Hello all,
CEL came on out of nowhere today. Codes are: P1481, P1300, PO303, PO305, P1129 pd, PO300, PO303 pd, PO305 pd. My throttle body gasket is leaking on the driver's side wires and plugs which are 3 yr. old Magnecore 8MMs and Bosch+4s. I have felt a miss for a while now but no miss codes have appeared until today. Could the coolant from the leak be shorting out the wires and causing the miss? Thanks in advance for any input.

My throttle body heater gasket took a dump a few weeks ago and leaked on my plug wires and caused a few mis-fires. I changed the gasket, and cleaned up the plugs and wires, and haven't had an issue since.

Coolant, leaking on your Magnacor wires shouldn't cause a misfire. Have you pulled one of the plugs, what does it look like. If I thought my wires were leaking, I would squirt all of them with water, when it is dark out, and see if any of them spark.
