The other day, I running the car in diagnostic mode to check if the engine was running rich, and noticed that in the DIC it continuously switched back and forth between E00 and E70 (this was after it showed stored codes). I wasn't sure if these had the same meaning as the normal codes since they were being shown after it put up the history/current codes. Also, I checked the read-out of the throttle angle; it was at 4.6 degrees when the pedal was not being touched and at 77 degrees with the pedal depressed all the way. Is this normal? I would have thought it should be closer to 90 degrees with the pedal fully depressed.
