* Crankshaft Position Sensor (CKP): This sensor tells the computer where the crankshaft is in its rotation. A failing CKP sensor can cause the engine to stall intermittently. It's a common cause of this type of problem.
* Cam Position Sensor (CMP): Similar to the CKP sensor, but monitors the camshaft. A faulty CMP sensor can also lead to stalling.
* Mass Airflow Sensor (MAF): This sensor measures the amount of air entering the engine. A dirty or faulty MAF sensor can provide inaccurate readings, leading to a lean fuel condition and stalling.
* Fuel Pump: While less likely if it starts easily, a weak fuel pump might be able to provide enough fuel for a quick restart but not enough sustained pressure during driving. It could also be a clogged fuel filter.
* Ignition System: Problems with ignition coils, spark plugs, or wires could cause misfires, leading to stalling. Though less probable if it restarts easily.
* Electrical Connections: Corrosion or loose connections in the engine wiring harness can cause intermittent problems, leading to the symptoms you describe.
* Computer Issues (PCM/ECM): In rare cases, a failing Powertrain Control Module (PCM) or Engine Control Module (ECM) could be responsible. This is less likely than the other possibilities.
What to do:
1. Check Engine Light: Is the Check Engine Light illuminated? If so, get the codes read using an OBD-II scanner. Auto parts stores often offer this service for free. The codes will give you a much better idea of the problem.
2. Professional Inspection: Given the intermittent nature of the problem, it's best to take your Intrepid to a trusted mechanic for diagnosis. They have the tools and expertise to identify the faulty component. Trying to troubleshoot this yourself without proper equipment can be difficult and potentially dangerous.
3. Don't ignore it: Continuing to drive the car with this problem could lead to further damage or a more dangerous situation.
Don't attempt to replace parts without a proper diagnosis. Replacing the wrong part can be costly and won't solve the problem. Get it checked out by a professional to ensure your safety and save money in the long run.
