You can treat your own illness but we pay doctors to figure out what's wrong. Same thing with cars. Unless you want to go through all the ongoing training mechanics go through, it's less expensive and more effective to have this kind of problem professionally diagnosed. Way too often I read that someone has come here for help after "trying" a dozen parts that didn't help.
We love helping do-it-yourselfers fix their own cars and I really respect anyone who wants to learn, (about anything, not just cars), but you have to provide a starting point so we know which direction to send you. We need you to tell us the same things a mechanic would learn from looking at and listening to your car. You also have to be able to perform the tests a mechanic would perform and relay the results of those tests back to us. So far the best advice I can provide is that there has to be a stored diagnostic fault code since the Check Engine light came on. Chrysler is very good about that. Some cars have Check Engine lights that turn on when the computer is "keeping an eye" on a developing problem but it hasn't set a code yet. That doesn't do any good. With Chrysler products there will be a code in memory unless the battery was disconnected or run dead, then that valuable information will have been lost.
If you cycled the ignition switch to get the codes, that only checks the Engine Computer, not any of the many other computers. A scanner is needed to access the other ones. Is it possible a code was displayed too quickly and you missed it when it continued on to "done"? I'd go to an auto parts store and have them use a code reader. At the very least, there should a misfire code that will tell you which cylinder is causing the problem. If by some odd chance there is no code, a full scanner will be needed to view live data to see the sensor data the Engine Computer is seeing.
