No none i also drive the car its only after a few minutes when the engine is off then when i try to start it starts but then the rev does not respond then i need to remove the plug from ecu again its a conversation from hilux d4d to lexus v8 vvti.

What device are you using to read codes? I've never had one with throttle faults that didnt throw codes. If the ecu doesn't throw codes thats an issue in itself.

The ecu has been prewired

I was meaning how are you accessing the information in the ecu? Like looking at data from ecu?
