This problem only occours when i fill the car up with gas. Right after I filll up (which is almost 50 with current gas prices) when I goto start the car it wont start. It tries to turn over but cant like the car is out of gas. If i press down the gas pedal to give it gas it will start after a short period of time, but still not even a normal turn over. Once it starts it runs like crap and the rpms wont remain constant at idle. after i drive for like a minute its back to normal.

anyone know what this could be
99 a4 qtm with 148k on it.

My guess is you drive a short distance to the same station to get gas from your house.

happens at different stations....one very short distance, another one 15 miles away

Did mine last summer - EXACT symptoms you are experiencing. Part - ~$60 at stealership, time to replace ~5 minutes. My recollection is that it was near the airbox. Good luck.
