Sorry to bring the thread back.
Joe how was the weather when this happened? Cold or warm?
I would suggest you take the car in. This one of the symptons of a blown coil pack or a coil pack thats about to blow. Usually happens in rather cold weather. If this is the case I say get in ASAP!
There was a problem with the coil packs at one stage and most of the GTi's ended up bursting in flames at a robot...
Just my 25 cents
