More than likely advance screwed up, what else is new
- 2004 Cavalier - 124k, owned since new
looks like someone needs to convert to external coils
i had the same problem with my Z24 but it was wen i was driving with the AC on and it felt like i was on two cylinders and i had to push the car to go , i check the coil packs the were fine, the problem was my ac unit it was total messed up, r u driving with the air on ? if so turn it off and see how she acts, if it sounds good and normal its the AC unit

Actually, it was the ignition module. Of course, it's something expensive. But it's fixed.
Question, did it sound like a harley motorcycle?
I am having problems with my car and the way you described your, It sounds like mine. Gonna have to check into this.
