My 04 Expedition has recently been hard to start and when driving I get a loss of power for about two seconds. RPMs go down to almost nothing, then the engine kicks in again and it goes up to 3,000. The battery light turns on for a few seconds then off.
i have no codes. I have a new battery and I have tested the alternator, but I haven’t been able to test it when the car loses power.
i have changed the fuel pump, fuel filter, spark plugs, air filter, and boots. I have cleaned the throttle body.
Any ideas as to what this could be? I’ve done a visual inspection of the fuse box by disassembling and then reassembling. I’ve inspected my battery cables but they see fine. Could this be the ECM? Perhaps a sensor is going?
