car gave symptoms of a coilpack failure on the way to work monday, barely made it to my shop and pulling into the parking lot it died on me. started it back up and instantly it reved to around 3 grand, then fluctuated between 3000 and 1700 and then it will die (running lean?), it did this before replacing the spark plugs and after replacing the plugs (they are gapped correctly). i also added two new coilpacks swapping them from cylinder to cylinder to see if i got a different result in the way it runs and nothing. im gonna try getting two more coilpacks and see if it that is the problem but from what ive been reading it could be numerous other things. until i vag com it i will not know exactly what, but im looking for anymore input on obvious things that might cause it to stall out. maf? crankshaft sensor?

From my experience with this car, vacuum leaks are numerous and often. Does your CE light come one? Might have a bad vacuum valve? They're really easy to replace but not so easy to locate which one sometimes. Have you tried running the car then spraying brake cleaner around the engine to locate the leak? The valves are easy to replace, but once you replace one, you should replace them all.

If it were a specific coil pack it would tell your 301 or 302 for cylnder 1 and 2 respectively. Sounds like a bad MAF, try cleaning it or replacing it.

it was indeed a vacuum leak, found it as soon as i checked the lines, just glad it was an easy fix

Glad you figured it out. Rest assured, it wont be your last. I'd consider ordering some online and start replacing em. Cheap fix and can solve a lot of future issues.
