LS Motor - Full Throttle Problem

[r00twayne]

Hello everybody,
We have this problem where if we go full throttle the motor bogs down completely, as in if its idle or gonna shut off. You go like 90% throttle the motor rips. I am thinking is a distributer problem but we haven't gotten a hold of another dizzy to try out. This is an obd0 ls motor running with a pr4 ecu.

Anybody else having any ideas? Only codes we are throwing are 1 and 14 (o2 and iac).

turned out to be our tps wiring, two of the wires had to be switched on the connector
