Question about 2000 Jeep Grand Cherokee
This could be one of many things:
1. Bad or dirty spark plugs. Oil could be getting on the plug tips and fouling the plugs.
2. Bad plug wires. Wires are arching and causing the plugs not to fire properly.
3. Bad electronic ignition. This could be a bad module,
4. Dirty fuel injectors.
5. Cam Sensor is bad. This usually happens after the car warms up.
6. PCM (Powertrain Control Module) could be failing
7. More more more
Check or have checked the OBD codes and verify the exact problem. This will tell you the cause and you can resolve the problem based on this result.
