1990 F150 4.9 computer re learn question
I had to disconnect the battery in my 1990 F150, to replace the starter & solenoid. After reconnecting the battery, it now has a rough idle/ off idle stumble when engine is cold. Smooths out after warmed up. Does the computer have to re learn the settings it had before power was disconnected? If so how much driving needs to be done before it's completed? I've driven it about 60 miles (in town & on highway with cruise on) so far since.
