Sorry for the confustion. I'm in Gauge mode watching 4 seperate Gauges (one of which is the Open/Closed Loop for the Oxygen Sensors). I know that hard acceleration will go to OPEN loop (per the documents), just not sure that hard deceleration should to that (It does part of the time).
I know I probably should change the fuel filter and possibly the Fuel Pressure Regulator to see if this helps, but wondering if the symptom I'm seing could be a clue to something else.
When I clear a code, I go back to Gauge mode and watch the 4 Gauges again. It may go 6Hours of continues driving with no codes (even stopping the engine and start again may or may not throw a code), but usually within 10min of starting up on the next day it will throw a code (Not always).
Hope that made more sense
