Transmission problem ?Cylinder miss ?

You should verify you have proper fuel pressure. Check with a gauge when cold and hot. Possible clogged fuel filter is not allowing enough gas to feed engine. Verify pressure at idle and also under load when driving.

How far over half? The idea that 220 is overheating is wrong. But I don't think your gauge shows numbers if I recall.
Check your engine driven cooling fan. Look at the fan clutch front and back. Is it moist and dirty? Oil from the inside may have leaked out. With the engine off of course, spin the fan by hand. Does it spin real freely and continue for a second or two or more after you let go. The clutch may be bad. What can happen then is the motor will spin faster than the fan and at time the fan will barely move and that would not draw air through the radiator cooling fins.
Also make sure the radiator and condensor are free from debris (leaves, dirt, birds, cats, etc.)

Fuel pump is located inside the fuel tank...

The fuel pump locking ring can also be removed using a brass drift.

two things bad idle air control valve,and the missfire is most likely an injector you can unplug there connectors one at a time to see which one after fixing you will need to clear eng codes any auto parts can do this

i would 1st check all of the vaccum hoses to see if 1 or more is leaking, or has holes in them, you can do this by running your hand along the hoses, but don't get into the fan. "while the engine is running , if you find a hose that is leaking and you hold the hole closed , the engine will run normal. then replace what defective hose, or hoses you fine, i had a friend that had the same problem, and his was a vaccum leak, hope this solves your problem.

threw the dip stick tube under the hood.

It will take the regular dextron type 3

try bart's radiator sealer, will help stop small leaks, can buy it at any auto parts store.

go to the bottom of the vehicle on the rear diff if your laying directly under the diff front being towards the motor back being towards the exhaust pipe tip, face the back of the vehicle next to the drive line on the diff usually the passenger side of the housing of differential there will be a plug if its not there its on the rear side plate.like i said im 90% sure its in the side of the housing anyway it takes either a big allen wrench or just a 1/2 ratchet with no socket to take off once you remove the plug get a smaller allen wrench,which is shaped like an L the shorter end dip it in the diff,if it comes out wet your good if not you wanna add carefull not to over fill i believe it takes 80/90 weight gear oil i havent been in a shop for a while but im all most positive its pretty simple the front if aplicable is the same scenerio

Jack up the vehicle ... take one of the front tires off.... roll it down the driveway and let it go... if it veers off in a crazy fashion one of the belts has shifted and the tire needs to be replaced... now do it with the other tire... replace if necessary.'

You should see the dip stick on the Driver side under the hood.It will be the only black steel tube that comes up towards the hood.The oil is sometimes poured down the same tube or it will be in the drivers side valve cover..
