Whenever I'm driving, I'm not able to drive consistently without the car stuttering (like I'm about to stall), which requires me to hit the gas pedal some more to keep it from slowing down on it's own. When I first had this problem, my friend and I did the built-in car analysis thing (turning the key on and off about 6 times i think) and it said my Oxygen Sensor was bad, so we replaced it with a used one from parts galore. It was fixed for a time (little more than a year) until recently, when it got bad again. My car doesn't stall as much as it use to, but it's quite annoying, so I bought a new sensor. Unfortunately, this did not fix the problem this time, though it did feel like it was running better at first. Any ideas?

Throttle Body Cleaning on vehicles without electronic throttle control (most 2003 and down)

You can in most cases repair this slow speed stall or unstable idle by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.

If you can make the problem happen in the garage I would check for spark at the plugs when it quits running. If no spark you will need to check the ignition components to find the problem.
It could be a relay or other electrical part.

down the dipstick tube!!!(really)DO NOT OVERFILL...
Your audi is fitted with a fuzzy logic gearbox, it will change according to your driving style.TRY THIS,put into 1st and without touching gas pedal, let the car accelerate to top gear,stop Then using onle 1/3rd gas pedal do it again.then using 2/3rds do it again.then only using the minimum pedal req accelerate to max legal limit.(try not to use brake pedal,let the car slow down itself,until you have to)then drive as normal, it will feel like a different car.

give it a oil change and put a new fuel filter on it. you might have to change spark plugs and spark plug wires. also put some engine and fuel treatment. if that does not work put about 5 gallons of premium fuel in.

Hello;
Have you checked your fuel pressure and volume? You may not be getting the ful sufficiently to the injectors. Also, change your fuel filter if you haven't already. Is the check engine light on?
Thanks;
