I think it would be best to call around for a repair shop that employs any technician who has ASE L1 certification, because the Neon may have misfire codes from many assorted problems showing up.
Try changing or looking at the plugs or getting a more precise scan from a shop instead of a parts store. The plugs, crank sensor, and many other parts, even more expensive may be bad. Ok Have you had it tuned up recently, it may need a tune-up. You can read all about how changing the plugs are part of this.
If you write down the codes and post your situation it would help. The Neon had some valve timing belt problems also.
Try and get a ride, take it slowly, at this point it may be better to trade it in, I know it is only 4 years old, but it is a smaller engine.
