i'm about to buy a 2001 f150 supercrew 4x4 5.4l, has had full synthetic from day 1 and only has 115k miles. was curious if anyone knew of any problems i might be coming up on soon if there are any that happen this early in the trucks life.
Not really. You're buying the same truck I drive and have no real issues. I aam going to have to put an IAC motor in it, but that's nothing major. I do occasionally have the PATS key problem but it's under warranty and really not a huge problem, more annoying at times. All in all, you're buying an awesome truck that will take anything you can throw at it while still being comfortable in a vehicle that looks great.
