Question about 2004 Ford F150
I have a 2004 F150 6 cylinder. The service engine soon light came on and stays on. But the truck is running fine?
If the check/service eng soon light is on a problem has occurred in one or more of the electronic systems of the emission system/engine management, it is very rare you will feel anything, the system has very good failure mode programming to keep that from happening, at this point the only thing will be that it won't pass a smog test, or the mileage may be affected. Have a test run to see which codes are present in the computer memory.
