Why do you have an occasional lack of spark in a 1997 Chrysler Sebring?

Answer 1

my original response to your question is below.. but it may be a spark plug, which would cost a lot less than the coil/cap combo. but its a good idea to replace coil/cap/wires every 100k miles.

Your Coil/Distributor Cap is going bad, replace it now before it dies and your car wont start. generally if you're at 100k miles they should be replaced, but mine lasted till 130k (it would misfire on acceleration and then it just stopped running). The Cap/Coil is located under the intake valve on the intake manifold, it is rather hard to get to without removing the intake manifold or the brake fluid resivoir. This is also a 250-300 dollar part(i know... owwie), but if it runs good otherwise its a good investment.

if your car doesnt have 100k miles on it this probably isn't your problem unless you've somehow shorted your ignition system out.
