If you have a tachometer, you can tell what speed your engine is running at idle. If you don't have a tach, you can probab;y sense whether the idle speed is too low. It may be that your minimum idle speed is too low. Chrysler 3.0 engines have an AIS motor AIS stands for "Automatic Idle Speed." That could be defective or badly connected. If you smell gas (check with engine off, under the hood), then you could have leaking fuel injectors which can cause hard starting (due to mixture too rich). How does the car run on at highway speeds (assuming it runs at all)?

Pull the spark plugs, one at a time, and note what cylinder each came from. See if any (or all) look blackened (may look like black powder on them, or wet black powder). Post what you find out. There is a lot of help avaialble on this website!

Something else to consider is whether the battery was recently disconnected or run dead. If it was, the idle speed will be too low until the Engine Computer relearns "minimum throttle". For that to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.

If this is the cause of the stalling, you also will not get the nice idle speed flare-up to 1500 rpm when you start the engine. The second clue is the engine will start and run fine if you hold the gas pedal down about 1/4".

If the engine stalls while driving, suspect the optical pickup assembly inside the distributor, or the ignition coil, but failure of either of them is very rare.
