I have a similar problem with my Jetta which is driving me crazy!! Any help would be greatly appreciated. My car starts and runs fine until it warms up, and come to a stop. After this, it will miss at highway speeds, and sometimes stall at WOT just like you turn the key off. I drive this car 60 miles to work everyday, and it runs great until I get almost home and stop at a stoplight. If I never have to stop, it will never give me problems. I have found out that when it starts missing, it quits when I accellerate or slow down. It will continue to miss at 55-65 MPH for the rest of the day. If I shift into neutral (auto trany) and turn the key off, and back on while driving, the miss will go away until I stop again. I can always tell when it is going to start giving me problems because it hesitates afert stopping. No hesitation=no problems. I did find a broken breather pipe from the front of the block to the valve on the valvecover and fixed it, but it didn't help. This car has 265k miles on it and has never had any problems until now.
