Code 998

[CManT1914]

I swapped the MAF out, and drove around. I got another CEL, and it came up with these:

KOEO:
334: EGR closed valve voltage high

KEOR:
998: Operating in failure mode

998, WTF??! What is "failure mode"?

Failure mode (FMEM) is when the EEC detects a problem with a sensor, and then switches over to it's failure mode. I believe that this mode is what is commonly referred to as 'limp mode'. I don't believe that there is a specific 'limp mode', but each sensor has it's own 'failure mode', which causes limp mode kind of conditions. You must have a wiring problem with your MAF.

Did you get the 113 fixed? If not, then perhaps you have a problem with that connector that both the maf and iat plug into.....

I'm thinking it is more likely the EGR, since it didn't throw a MAF code this time.
