Interesting......I'm experiencing the very same problem with my 95 mystique V6. The symptom is sparadic and the check engine light is also sparadic. I just replaced the plugs last night and the test drove it and it was actually acting worse. This morning on the way to work, a 20 mile run, it didn't miss a bit??????? I haven't been able to scan the car yet. I'm suspecting now wires or coil pack. It seems to occur at low rpms ( under 3500) under load and pulling out. It is ok under load above 3500. Is this similar to your condition?
