1994 90 Q stalls at stop signs...

[199490Q]

I have a 1994 90 Quattro 5 speed with 397,000 km on it that stalls when I stop at a red light or stop signs. Not all the time, but most times. There is an oil leak which I haven't found (I just keep toppin' 'er up when i fill the gas tank), but other than that the car runs just fine. Any ideas out there about what might be going on?

do you have a check engine light? mine doesnt stall but sometimes my idle drops to 250rpm and i had it scanned at the stealership and they said it was my throttle position sensor
