these are the codes
P16A0 ?
P0113-intake air temp sensor high voltage
P0102 Mass air flow sensor low frequency
P00F4 ?
P0097 IAT sensor 2 circuit low bank 1
P2127 Acc pedal position sensor 2 low voltage
P2122 Acc pedal position sensor 1 low voltage
I now have the reduced power, CEL, rough idle with or without VTC connected.
what I have done.
-disconnected throttle body connecter and checked wires are secure
-gave the Mass air flow sensor a wipe with clean micro cloth
-removed butterfly assemble and wiped. operated freely but wondered why it was not fully closed.
-pulled fuses for ecm & tcm
Now it is all back together and the battery is disconnected for overnight
any suggestions?

With all the codes that would not have anything to do with the VTC I would imagine you have another problem. You should never wipe your MAF sensor, the wires are delicate and you can damage them, soak it with MAF cleaner and let it dry before reinstalling it. The Throttle body should not go completely closed. The engine needs to get some air to start and idle.
It almost sounds like a low voltage issue. Something could be dragging your voltage down.
