Lack of power
My nephew just bought a truck, he has an issue, and I'm stumped. I did a search, but came up with nothing. (2001 ext cab f350 7.3 4x4)
When the truck starts, she smokes a lil blue, but nothing serious. But if he lets it sit for a few days, when he starts it, it will start a lil rough, idle up. After a normal warm up time, you take off, and she's got nothing. You have to pop it in neutral, hold it to the floor, she'll reluctantly rev up, and once she gets above 2500 she'll pick up and gain to 3g's. once he lets off, throw it into gear and she responds fine. If he drives it everyday, it's not an issue, only when it's been sitting. Any idea on what to look for?
