Try cleaning the EGR valve first

Potential Symptoms

Symptoms of a P0118 could include:

* Very poor fuel economy
* A no start condition
* Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
* Illumination of MIL
EGR valve

Usually a fault in the control circuit, will leave no noticeable symptoms other than the Malfunction Indicator Lamp (MIL) illumination. However, if the EGR control solenoid
is stuck open due to debris, etc. the code may be accompanied by misfire under acceleration, rough idle, or engine dying altogether.

SOURCE: running rough

If your car is running rough and it's fuel injected (which yours is). Follow the air intake (black plastic box - housing the air filter that has tubing that goes to the motor) until it reaches the Throttle body (rounded metal air intake at the end of the plastic tube - has one large flap inside). You will want to remove the hose clamp and thoroughly clean the throttle body and the AIC (air idle control valve - small canister attached to the throttle body). Use off-the-shelf cleaner from any automotive store. This takes about 30mins to 1hr depending on your skill level. This will result in a cleaner smother idle and smoother performance. This is a common issue in today's cars. I have to do this once a yr to keep my modified car running happy.

Take a look at the later parts of this article for pictures to give you an idea:

SOURCE: 2003 Dodge Neon Code P0551 and Rough Idle

I HAD THE SAME PROBLEM WITH MY 2002 DODGE NEON. THE FIX WAS TO REPLACE THE POWER STEERING PRESSURE SENSOR SWITCH. IF YOU DO IT YOURSELF IT WILL PROBABLY COST ABOUT $50 OR $60 INCLUDING THE HAYNES MANUAL TELLING YOU HOW TO DO IT. I BELIEVE THE SWITCH COST ME ABOUT $30 OR $35 FROM A DODGE DEALER. IT IS PRETTY SIMPLE. TAKE OFF THE ELECTRICAL CONNECTION GOING TO THE SWITCH AND THEN TAKE OUT THE SWITCH ITSELF WITH A PROPER SIZED WRENCH. THE SWITCH IS THREADED INTO A CONNECTION ATTACHED TO METAL HOSES THAT HAVE POWER STEERING FLUID IN THEM. HAVE THE NEW SWITCH READY TO PUT IN AFTER THE OLD ONE COMES OUT,FOR POWER STEERING FLUID WILL FLOW OUT OF THE CONNECTION. PUT THREAD TAPE ON THE THREADS OF THE NEW CONNECTION. THIS WIIL HELP TO SEAL THE SWITSH FROM LEAKS. TORQUE TO SPECS AND REINSTALL THE ELECTRICAL CONNECTION. CLEAR THE CODE AND SEE IF IT COMES BACK. MINE DID NOT. OH YES, IT MIGHT BE A GOOD IDEA TO HAVE SOME POWER STEERING FLUID TO TOP OFF ANY THAT LEAKS OUT DURING THIS PROCESS.
GOOD LUCK!

My 01 neon did the same. I am in the process of replacing all the engine mounts. But if you have done this already it could be alot of other problems. Does it do it most when your idling?

This is either the sensor or an open/shorted circuit leading to the sensor, you need to use a dvom to check it or replace the sensor and atleast eliminate that fault
