Diagnostic Help! (Code deciphering needed!) 850 1994

Hey guys,

My wife's car nearly died on her today. She was just driving along in the city and it puttered out and died. She was able to fire it up and limp it home, but just barely. I tried driving it later today and it would barely run below 2K. Missing on several cylinders. Very rough idle and would not stay running if I wasn't feathering the gas pedal.

I only found codes on the A2 socket but it was a long list of them. I could only decode a few of them, could someone here help me with the rest?!?!

121 - Faulty MAF
414 - Boost pressure too high (?)
543 - Missfiring on at least one cylinder (for sure!)
451 - ?
455 - ?
454 - ?

Can I get some help decoding those last three and maybe some thoughts as to the source of this problem? Thanks!
