Default Engine Revs

So today i noticed that when my truck is running in park, and also when im stopped in gear, the engine keeps reving up and down. Does anyone know what's causing this? Also i did the throttle cable mod a couple of weeks ago, would that be what's causing the engine to rev? Thanks

turns out it was just a leak in one of the hoses going to the air flow sensor

I bought the truck from the OO in 8/1/2013 for $900. It had a burnt exhaust valve. I just threw some heads on it(5/1/2014). Ford has many good engines, the 3.0 Vulcan is not one of them. I bought it for the price.
