Engine Performance problem
1998 Audi A6 6 cyl All Wheel Drive Automatic 242K miles
My 'Check Engine light came on, the computer read was 'Large vapor leak'. 1st the gas cap was replaced with a new one. Check Engine light stayed off for a couple of days before re-lighting. Next the vacumm pump location in the rear wheel well (driver's side) was replaced, light stayed off for about a week. Now light is back on.
Also at refueling I have to press on the gas pedal to get get the egine started. Once it restarts I don't have any problem restarting with just a turn of the key until the next fuel re-fill.
Any ideal what the problem is?
have the same problem?
