This problem sound familiar to anyone? more..
 

'02 Sedan. 22k.

Sitting at light idling, car just dies. Typical hot humid FL afternoon day about 6pm.

Restart car, seems ok, then driving along about 1/8-1/4 mile, just cruising about 40mph, and the car starts to miss/shudder for a sec/two, the CEL light flashed on then off. Then, car continues as normal.

Next day, idling with A/C on and checking the car with VAG. No faults found. After 10 minutes of idling, the car hiccups like it is about to die in Park while idling. Tiptronic. But, it somehow recovers without stalling, probably cause I was in drive the first time at a light the evening before.

GIAC ECU, Tip Chip. Only mods.

Thank you.

bad gas or water/condensation in the tank. clogged fuel filter. any number of things.
