Randy. It sounds like a bad connection at the back of the control head (Chrysler talk for the actual cd/radio, sat nav)
If you have the courage to gently remove the silver plastic surround with a blunt knife by prising it away from the dash ( this process is on the net with good photos) you will observe the 4 screws that hold the control head in position. I would unscrew them to get to the back of the unit and remove the 20-40 pin connector then push it home again a couple of times. You could spray a little Servicol electronic contact cleaner onto the connections. Be careful replacing the silver plastic surround as it is designed to break

Is your engine management light on (mil) test it with obd scanner for code if light is on. If not you might have an air or a vacuum leak. This is very common! Open the hood and listen for a hissing sound when the engine is running. Unmetered air can enter the engine through a vacuum leak, a dirty airflow sensor that is not reading airflow accurately, an EGR valve is not closing and is leaking exhaust into the intake manifold, an EGR valve that is allowing too much flow. If it is hard to pinpoint take some brake cleaner or starting fluid around the intake manifold and vacuum lines and see if the engine stumbles or if the idle is affected. Be extremely careful when doing this!

Also, your throttle body may be carboned up and need to be cleaned! This can cause all sorts of idle and hesitation problems. This is caused by the throttle plate not seating properly. The First thing i would do is clean out the throttle body with some throttle plate and intake cleaner and a small brush.

Another common cause would be the Idle Air Control motor. This is very common on older cars. The IAC motor gets lazy and cant keep up with the fast idle changes. Also when the IAC motor is out, I rec to check the passages for carbon build up. If they are plugged they need to be cleaned out.

Possible Causes
Check for air leaks in the Air Induction system (e.g., in the intake manifold)
Check for air leaks in the PCV system and in its related hoses and/or valve
Idle air inlet passage or throttle bore is dirty or full of deposits
IAC valve has failed
Throttle plate, throttle shaft or linkage is damaged or sticking
TP sensor is out-of-range or "skewed" high

Did you put back. Pulling a fuse will not reset the light you have a problem the only way to do that is find out what is wrong. I think starting problem was caused by pulling the fuse. Put fuse back and give me an update

Are your battery connections clean and tight? I'd disconnect the battery and check the ecm harness if that didn't work. Good luck man.

If you are referring to the trunk lid, pull down the back seat, crawl into the trunk and pull the emergency trunk release.

Struts...Shocks.....Hard hitting and wanders off on turns...push down hard on the corners hard. If it comes up sluggish or bounces....any shop should check for no charge.....get them fixed.... They\'ll loosen everything on your car and cause issues later....

There is no fuel filter that the car owner can replace as a maintenance part. The only filter is a sock filter in the gas tank.
