It's a 1992 Chrysler Lebaron and it runs fine when it first starts up. But once it is at normal operating temperature the car starts to misfire. It doesn't stall so I'm not sure what it is. It misfires when you are driving and at idle so I'm stumped. It is my sister's car and I'm in a different state so I haven't done anything to it yet, just trying to work this out in my head before I get there. Thanks for the help!
Yes friend, that misfire is just that. Called a dead cylinder. Could only be a dirty or faulty injector. Do a ohm-meter test on the unplugged injectors and a compression test on all cylinders with all plugs out if you don't find a faulty injector. Could then be a faulty exhaust valve needing attention.
SOURCE: misfiring
Well there are several things that could cause this problem...
1. one of the coils may not be firing.
2. the ignition module could be bad.
3. the mass air flow sensor could be tellign the car to run rich (too much gas)
4. if the car is equiped with a map sensor it could do the same as a mass air flow sensor.
5. fuel pressure regulator could be leaking at vacuum port drawing in more fuel than needed.
6. the computer itself could be bad as well.
The car either has a map sensor or mass air flow not both. The mass air flow would be right after the air cleaner housing usually a 4 wire connector. map sensor is normally located on the rear of the upper intake manifold with 1 vacuum line going to it with 3 wire connector. Hope this helps.

Have this car fuel injection ore carburettor?Are the electrik fan on the radiator? What are the temratur gauge showing whwn the engine overheat? are the car overheating when you drive? If the are el fan , you must check if the fan get 12v when the engine are warm. If you not get 12 v you must check the sensor som start the el fan.
Another things coul be the water pump, ore the termostat. Did you use glykol (anti freze) ore only water on the radiator?

I had a similar problem with my 90 LeBaron. It turned out to be the computer.

#7 cylinder is the 3rd cylinder back on the drivers side you might have a bad coil thats what i would replace first unless when you take the coil out there is oil on it if so your valve cover gaskets are leaking you will need to fix that first
