Exclamation Engine Codes P2104 Forced Idle P2112 Stuck Closed

I am trying to troubleshoot what is going on with my 2007 CX-9. Also had 3 codes on coils A, E, F.....Has anyone encountered this issue? Everything I have read leads to electrical, but I think the Cat is damaged. Any help is appreciated.

P2104 & P2112 both lead towards a faulty throttle body.

What are the Coil codes?

There are two Cats, 1 for each exhaust manifold.

@ grim_reaper Ignition Coils A-E-F PRI/SEC Circuit Fault P0351, P0355, P0356. The coils look terrible burnt up and cracked. I could barely get A or (first left coil closest to firewall out)
