My repair shop cannot find the problem with my Golf with the 2.0 engine.Once it starts to warm up a little, it misses badly between about 2000 and 3000 RPM. After it warms up even more, the problem lessens. If it sits for several 4-5 hours it comes back. So far, they have replaced the distributer and cleaned the trottle body. They have swapped numerous parts and found not that have affected this. They found me another main computer (used since I wasn't willing to take a very expensive bet on the new one that they wouldn't take back if it didn't fix the problem.) That didn't fix the problem. The latest try was described to me as a replacement of the device that tracks the position of the gas pedal. Again, same result. They've had my car once for about a month. Now I'm getting ready to take it back again. (They left the last ticket open since they weren't sure it really was fixed.) I think I need some more ideas for them.
