I can roll around just fine if I don't get heavy into the throttle, but if I do any strong pulls it will continue to run apparently normally up until the point that I let it go to idle, and then it just shuts off. I'm having trouble with the car cutting off at idle after any 'spirited' driving. My kid is super stoked on the MK4 JTI and I would otherwise be happy with my newsed purchase with the exception of one particular issue. Sold the MK4 that I've been driving for a little over 4 years to my son, and I picked up a tastefully tuned MK5. Hey folks, I've been around the MK4 forums for a bit.
