Misfiring Throws the 0300 code but shouldnt it be a specific cylinder? V70-XC70 2004

The plugs were a cheap try, why not. It gave me a chance to see that none were soaked with gas or antifreeze, so I was able to rule that out.

I did get the 0303 and 0305 about 2 years ago, and as you said it was the Fuel Pressure sensor. I replaced that and problem was solved back then. Strange thing was I never felt any misfire when those codes were coming up back then.

This time it is the 0300 random misfire, and it runs with a skip that seems to be very nonrandom. It also is more pronounced at lower RPMs. At times I can get the car up to 6k RPMs and it seems almost ok, but then it goes into in a sort of limp mode and restricts the RPMs to about 3k. This causes me to have to restart the car while moving, and then it allows the RPMs to get higher than 3k again for a short while. This car is a manual trans.

I received the Cam sensor yesterday and tried that with no luck, as Klaus suggested would probably be the case. I am hoping the coil pack I ordered shows up today and I will try that on top of each plug. If that is not the problem, I think I may be SOL, which would really be too bad because this car is spotless inside, seriously comfortable, and gives me 30mpg even at these miles(225kmi)!
