Newly bought v6 4motion is poorly

[MWBV6 0]

Carrying on my thread in here if i can as this is really the correct place for it.

Bought a v6 4motion.

Went to drive it for really the first proper time on friday and it shut down

Eventually got a friend to plug his diagnostic kit into it and it came back with the following codes:

P1579

P1564

P1543

P1172

All these point to the throttle motor or sensor.

Got hold of a relay diagram earlier, would it be worth swapping the relays to see if this is the cause?

Or does it go deeper???
