They replaced one of the 3 valves in the system (said it was rusted) and cleaned out (sprayed) the manifold. Obviously what they did didn't fully resolve my CEL issue.
It goes back on Monday. I'm sure they will suggest replacing the other two valves in the system and I might suggest they either clean the MAP or replace it, since I've read that can be an issue too.
Other than that, my 98' with 75,000 miles runs great....in fact except for the CEL I would have no idea I have an issue........just don't want to waste any more $$ or time.

Your MAF has nothing to do with either code.
The two codes are indicating that the SAI pump is not triggering or does not work.
Possible causes: - Wiring harness of fuse issue
- Relay not working
- DME fault
- Air supply lines plugged
- Pump itself has failed
- Change over valve failure
