Pull off the throttle gently, pay real close attention how the metal gasket is oriented. It needs to go back the same way or your truck will explode:
Next, we will remove the upper intake manifold. Make sure to give it a good stare before you start. Nice, hard, evil stare. You're going to own that intake manifold. It's yours. Touch it. Feel it. Be the Manifold:
To remove it loosen these brackets that hold the speedometer cable:
and these other brackets that are on the driver's side of the manifold. (the bracket with the blue paint might need to be removed from the other end if you cant fit a ratchet at the upper bolt):
disconnect this hose at the far end of the manifold, on top:
Next, remove all the other bolts that hold down the intake manifold - Not pictured. Manifold should then come off.
Now time to remove the lower intake manifold -
If for some reason you couldn't take the speedometer bracket off due to it being too congested, you can take it off now:
This stainless tubing has hose attached to the ends, take off the hose. I didn't have to remove the tubing itself, just the hose.
Remove the computer diagnostics port that is attached on the driver's side of the manifold:
At the back of the lower intake manifold, there is a bolt holding the wiring harness, remove it.
At this time, the bolts holding the lower intake manifold can now be removed.
Remove the remaining bolts holding the lower intake manifold down:
Once the lower intake manifold is removed, cover up the exposed intake chambers with a rag, tape, etc to prevent stuff from falling in there. You do NOT want a bolt falling in there. Might as well jump off a bridge:
Moving onto the passenger side valve covers, remove the spark plug wires and coil packs:
disconnect the injectors:
Remove the bolts holding down a wire bracket - This will not be able to be removed completely, but taking the bolts off will make the job easier. It will give you room to work with.
