sounds like you have a vacumm leak... check all hoses if they are good check the gasket.... go buy some brake parts cleaner and spray around ... it will find the problem area!!! let us know

little update
I tried the break parts cleaner trick and basically sprayed around no knowing what i was trying to look for but i was able to get my car scanned and it brought up the following codes:
P0108- manifold absolute pressure/barometric pressure circuit
P0101-mass or volume air flow circuit range/performance problem
P0135-02 sensor heater circuit malfunction (bank sensor 1)
P0141-02sensor heater circuit malfunction (bank sensor 2)

feel on the back of the intake and make sure that nobody messed up your map sensor. what your looking for when you spray throttle body cleaner or brake clean around the intake is a rise in rpms. when your car is falling on its face at idle and you complain about vaccum leak and what not, the cleaner will act as raw fuel and run into the intake ports on the heads, go into the combustion chamber and get burned which cause a higher and smooth idle for a second. when the car is on do you hear a hissing sound under the hood?

i tried the break parts clean trick the other day but it didnt make any difference in the miss firing. I just took off my intake to look things over and discovered water built up around my head bolts and my intake was damp inside, anyone have suggestions on how why this is occurring?

i beleive i found the problem to my miss firing and idle problems, i found out that i broke the oil pressure sending unit at the back of the block.
Could this actually cause all of the problems iv been having?

No a oil pressure sending unit will not be your problem!!!!! Your head bolts are under your valve covers.. So did you take your valve covers off to replace your intake?????? It sounds like you have a coolant leak there are coolant bypass hose's under your intake,, while the intake is off pressure test your cooling system and you will find your leak but it does sound like you do have a vacum leak coming prob. From one of your vac. Hoses on the back of the intake check the pcv vac. Hose at the back of the intake they get old and brake apart if you move them the slight ist!!!!

lil update, while installing my intake i accidentally torqued one of the intake bolts a little too much which made the intake hole to be pushed down and cracked a little
here is a pic of the damage:
(first two are blurry, my camera wouldnt adjust to the light
)
Would i be able to still install the intake with it being cracked that much? if not how will i be able to fix this without buying a whole new one

use epoxy and seal it up. you dont have to torque them down that much. you must have really cranked on that. i use and air ratchet when ever i swap intakes on vehicles and havent even broken them.

well remember we told you in some of your first posts, take throttle body cleaner and spray it around the intake and see if the idle will raise and idle smooth. yes intake gaskets should be changed every time the intake is removed and replaced. some may say other wise but its just to cover your ***.

Iv replaced all of the gaskets and it still is misfiring, so i removed the intake again and found that there was this black oily ring around the last 2 head ports.
Could this still be a vacuum leak or could it be something else?
