multi codes again

2002 Volvo S 60 non turbo
car died couple months back code for MAF, and codes for multi misfire and TPM. Changed out MAF. Car ran like Poo, stuttering missing chugging.
Nearly undrivable, then it went into limp home mode. ( I think it was limp home, no real throttle response, 10 moh max downhill. Got tit in for service to local foreign auto specialist. Changed out TPM, checked plugs, coil pakcs fuel pressure, all good still chugged and no acceleration. Garage towed it to dealer to have TPM reprogrammed. Dealer said needed coil pak and plugs, reprog everything. Car ran fine, couldn't get a real answer from the dealer as to what the problem was.
Two days ago driving into work car when from running great to crap. CEL went on, no accel, missing, etc etc etc..
It was like someone flipped a switch.
Code scan came up with the following.
P0300, P0446, P0205, 0204, 0203 ,0202 0201.
Pending codes 0300, 0446, 0205, 0204 ...etc.

One other thing that appears
The mesage center n the left of the display gets all staticy and jumbled. It looks like it's writing in some alien language, or sometimes just random dots.
i hope this isn't an ECU. The last go around was $1400.

I have never really had trouble diagnosing these cars, If I can't do it with an OBD tester I can usually figure it out with a schematic and a volt meter.

After all the repair money spent in the last couple months, I would really like to know what the real problem is, and how and where to start fixing it. The car is immaculate inside and out.

Thanks, David

You probably need a new ETM (throttle body) and REPLACE the breather system.
Get the codes with VIDA and have the ETM sweep test done at the dealer.
No other way around it unless you have VIDA and know how to actually use it and MARK your MILEAGE down

The ETM was replaced with a new unit, I'm sorry I keep referring to it as TPM. Throttle Position Module. That alone was $400. It's the white dot version. It was matched and reprogrammed at the dealer.

There are no NEW white ones, haven't been in over 10 years.
Were all the tests done and properly?
I don't know what all the codes are but if your breather has never been replaced, I'm sure oil is going over everything and the oil is continuing to foul up the works
MILEAGE????????????????????????????????????????

Mileage 140K, ETM was gotten from dealer from in house stock, so I'm not sure how it could be bad. Plugs clean. I ordered PVC kit and will do this weekend. I don't understand how this could be a cause of all the codes thrown, but I'll give it a try. It was done once before.

Okay Breather system replaces. Damn stupid design. Injectors cleaned, new oring, still runs like crap. Misfiring shuddering, Message center still displaying gibbereish, sometimes it tells me to upshift. CEL flashes on and off. Tranny shifting is not right. Sometimes almost dogs to a stall and then drops gear.
Any other Ideas anyone? The codes all seem to be injector related. with the exception of po446 and po300. How do 5 injectors fail?
What am I missing??
P0300, P0446, P0205, 0204, 0203 ,0202 0201
