IT'S Running REAL BAD

[Black04edge3.0]

Hey Guy's, I'm new to the station but I have a problem already!
I have a 2004 Ranger 3.0 automatic .While driving the truck it started to shake and miss and the check engine light came on, so I limped it home, and bought a code scanner(Actron OBD 2 Pocket Scan) and I have the following codes:
Set: P0300,Random/Multiple Cylinder Misfire Detected
p0305, Cylinder 5 Misfire Detected
p0306, Cylinder 6 Misfire Detected
Pending codes: p0175, System too rich bank 2
p0301, misfire cyl. 1
p0302, misfire cyl. 2
p0303, misfire cyl. 3
p0304, misfire cyl 4
p0316, Misfire detected first 1000 RPM's
any clues to what may cause this? I pulled plug 5, it looks old, and smelled a little of raw fuel, but it wasnt' soaked with gas or carboned up(truck has 60,000 miles on it) I hooked up the plug wire and had my girlfriend start it up and it had a nice blue spark, looked o.k. I checked all the plug wires and looked for vaccum leaks (I did not spray any carb cleaner around to see if the idle changed) The truck is stock except for a "little" modifacation to the air box.(has a few extra holes in it) It runs bad at idle and in the upper rpm's and has a slight ticking sound, kinda like an older non computerized engine with the timing out or bad plug wires. It run sooo bad I'm affraid to drive it and screw it up more
I just bought the truck a month ago, and don't have any maintenance records, and of course I did NOT buy the extended warranty(cause its a Ranger "it will run forever") I'm on a low budget so any help would be greatly appreciated!!!!! Thank You E-mail blacksabre@yahoo.com

When i bought my '02 it kinda did the same thing, I was getting a random miss, cyl 3 Miss and one other miss code that I cant remember, the truck would would hesitate, you could feel it missing while in the throttle and shake at idle. anyways I got a new coil pack from Autozone for like $70 and it fixed it right up.

This is similar to the issue I'm currently having. Did replacing the Coil Pack correct the problem?

Basically misfiring on every cylinder.

Replace the spark plugs, plug wires, and coilpack...in that order.

Might "illuminate" the problem if you lightly spray the plug wires and coilpack with a mist of water with the engine running, in the dark. Look for arcing.
