I got a 2013 F-150 5.0 with 110k miles on it. Every now and then I値l turn the truck on and the gas pedal is a little stiff and the steering wheel has a little tiny bit of resistance. I値l run it that way and turn it off. Start it up again and the gas pedal is so sensitive I知 doing 70 and not realizing it. And the steering wheel is a lot more loose. Could I be having electrical problems or alternator problems?

 

What is the voltage of the Battery while off and then after you startup the truck? Does it make a difference in the power output, while connecting a Voltmeter at the battery, in the voltage that is registering?
If the Alternator and Battery are working right, this is what you should see:

12.6V or so should be at rest, engine off.

Shouldn't go under 10V on start up.

Should be running @ 14V or so while running.

When you turn off the Truck you'll have @ 13V at the Battery, surface charge, and that number should go down to 12.6 or so.

If all of the above is good, discard your alternator as a possible culprit.

 

I know I知 getting 14 at start up and after driving around it値l go down to 12.50-12.80. So I知 wondering if my truck is in 4wd sometimes now
