I have a 2000 A8 that is very well maintained. As background probably to eliminate as a cause of this issue, within the last two years I have changed timing belt/water pump/fuel pump/fan/mass flow sensor and 2 oxygen sensors. The car idles between 650 -1000 rpm when stopped and when codes (throttle body /acceleration over threshold/mass flow sensor/oxygen sensor?) are cleared, I get 200-300 miles of a perfectly running car then it starts again.......my mechanics who are really good (I think) have also taken out and cleaned the throttle body.....HELP I NEED A SOULTION..
UPDATE
After reading a post yesterday, I disconnected the battery for about 1 hour, reconnected and turned the ignition on for about 2 mins to recalibrate the throttle body. The car ran smoothly after that until I got home. This morning the problem reappeared but not as fierce as before.......could it be that I have to replace the throttle body? Any suggestions from anyone out there?
