Ever have that early morning stumble where truck sits all night and you go to start it up and it stumbles around a little or you go to put it into drive and start to go and it stumbles? Well I think I found the answer! Was reading on another site for a different ford truck and... over time the intake manifold gets loose, try retorqing the bolts that hold the intake plenum to the intake manifold, snug it down some. Also your EGR you may have cleaned the hole that goes from the EGR into the intake plenum a couple years ago, but over time that hole gets clogged back up again. If you got a stiff piece of wire/concrete bailing wire try inserting it in that hole if it only goes about an inch and stops, its clogged that wire should feed all the way in about 3 inchs. How you can check to is take a air gun and open the throttle plate air should flow freely from the outside to the inside, if it doesnt its clogged, get some intake cleaner or carb cleaner and start cleaning, keep poking that stiff wire into the hole until it is cleared, air gun blows free and clear into plenum. Ill tell you my truck runs like as some refer to it a raped ape, ive increased power, goes up hills without issue.
