Both 47 and 56 could cause your issue. 56 doesnt effect later ecu but it causes rev issues on your early ecu. Ive outlined how to sort that so not going over that again. Code 47 i would guess either you have got wiring wrong or you have a sensor or maybe ecu fault. I remove trac and wire the ecu as a non traction control unit as per my diagrams. I find it easier to delete system and i think it makes the engine look a bit tidier. I cut the sub tps off, put a fitting into the hole and use as the air supply for the iac. To sort i would be comparing pin voltage charts to readings from your vehicle. Good luck.
