Radiator busted, now misfires on cylinders 5 & 4

[jac]

Hello gents,

I need your help to see if I finally managed to kill the engine or just have other issues with it.

While driving in town, the radiator developed a crack and the engine overheated. I drove it about 4 miles in total, going about 10 miles/hour and stopping to cool down every half mile or so until I got home (probably damaged the engine doing this - see codes below).

Anyway, I parked the car for about 3 weeks and I just installed a new radiator yesterday, refilled and bled the coolant, and got the cabin heater working too.

Took it for a spin just now and several lights came on: SES, DSC triangle, Brake [Red], ABS - And of course the car is limping.

The codes it is throwing are in various subsystems:

[DME]
242 - Misfire cylinder 5, misfiring with cylinder cutout (Misfire CARB_A)
241 - Misfire cylinder 4, misfiring with cylinder cutout (Misfire CARB_A)

090 - Exhaust temperature before catalyst bank 1, signal line, short circuit to negative. (Shadow memory)
091 - Exhaust temperature before catalyst bank 2, signal line, short circuit to negative (Shadow memory)
093 - Exhaust temperature after catalyst bank 2, signal line, short circuit to negative (Shadow memory)

[DSC]
15 - Recirculation pump error

[IKE]
189 - Electronic braking force distribution

[ZKE]
167 - Mirror, potentiometer horizontal or cable, passenger's door
128 - Servo-valve or wire, open circuit
112 - Servo-valve or wire, open circuit (shadow)

I am going to run a smoke test, and play "whack-a-mole" with the coils. Will report back.
