Message Need to figure out why the Translator seems to be in Dummy Mode.

Also Hunt down why you can't see two O2's.. the chip should not effect that..

While the Car is idling warm, pinch off the Big tube feeding the Balance crossover in the Middle.. That should be the Air Regulator Feed.. that will prevent ANY air from coming from that device, and will prove if that is your High Idle Issue.. I've put a Plug in mine, and are just using the Other two Devices to set Idle Speed.. The Air Regulator is a Left Over from Carburetor Electric Choke Days.. the A/C Idle Up Sol. and the IAC can control the Idle Speed.. Better in my Opinion..

I've never dealt with ECU Codes VS PTU Delete, so I can't help there..

Look at your Fueling Trims in Conzult , and see where they are running you said 80%?.. that that your Fueling Trim?..
