The car is hard to start and does not hold idle very well. It is running very rough with no power any suggestions? I have tried different coil packets with no difference. It stumbles and surges with no consistency would the ecm do that?

Vehicle: 2000 ford focus 2.00 doch

The ECM is the last thing to test or replace. Start with the replacing wiring and distributor

- Faulty Ignition Coil 1
- Ignition Coil 1 harness is open or shorted
- Ignition Coil 1 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
