Default Codes P0107, P0108, P0121 on 1997 Park Avenue

Driving my 1997 park avenue to work the other day. It was raining and the ses light came on. I did not notice any change in performance of the car, and the fuel mileage did not change, so I figured it was just a connection getting wet. Since then it has been dry weather but the light is on and off at times. Read the codes with a scanner tonight and got the three codes P0107, P0108, P0121. Any ideas?
I replaced the pcv assembly 30k ago.
Car has 243k on it, trying to make it to 300k.
Please help.
Thanks in advance
