Service Engine Soon Light is really nothing to worry about if you service your car regularly. All it tells you is that routine maintenance is due.
However, if it says Check Engine, which I suspect it does(I haven't seen a Chrysler product with a Service engine light) you have some sort of malfunction that needs attention. You can take it to many auto supply stores and have a code reader hooked up for free and find out what he problem is.

On a 1998 Neon you need a code reader not only for the problem but to turn the light off after you fix it. The problem is most likely your oxygen sensor which is code po142.
