Big Lose of Power
Take off your throttle body, get a little dental mirror and a flash light, look for "pools" of oil, check all around, including the corner's. If it's all nasty and dirty that's a good sign you need a plenum fix. Haven't you already fixed the gasket but not the plate? Or is that someone else I'm thinking of?
Does your truck use excess amount's of oil?

If/when you have to repair the plenum replace BOTH gasket and plate!!!
Just pull the throttle body and do some pokin around, see what you find. Some plenum's are blown like crazy other's not so much. So IF you have the problem, your oil consumption may not be all that much compared to other's.

No too sure about power, but if your plenum is gone then the O2 Sensor will be bad or going bad and will affect your gas mileage.
How many miles are on the motor?

I just put a new o2 on the I put a new one on at the begining of the cat I forget the name of it and it is running better. It is still a bit sluggish I guess I'll do the pump next then well check the plenum

Another thing to consider is the timing chain and gears! I'll bet there's some pretty good slack in it after all the years, unless it's been replaced at some point in time....
It has 165k by the way

An old saggy timing chain will effect how well the engine responds. That could be part of the problem. And timing chains aren't terribly expensive, even the double roller ones they HeyYou seems to like 
He'll tell you that was the single best thing he did to his truck, performance wise.
