Is your MAS plugged in? Both of those codes mention the Mass Air Sensor, and you probably unplugged it and removed the intake plumbing to put in your master cylinder.

 

I put everything back together but i will check..i have an SRI. and just took off the Filter..so i will have to recheck everything...........thats all?

 

Try unplugging and replugging your MAS, then. Double-check the hose clamps on your SRI, too. Then reset the ECU or use a scanner to clear the codes and see if they come back.

 

Its pretty common that the cause is a bad connection to the MAF, also, the MAF not sealing properly and the one that happened to me was that thye MAF was a bit dirty... This one you can correct with ELECTRONICS CLEANER, comes in a spray can. You just take the MAF out again, disconnecting it first then spraying it OUTSIDE the
