How long since over-all tune-up? Code 22 has to do with throttle postion sensor/wiring circuits. Code 32 has to do with egr. Code 35 has to do with idle air control.

With the code 22, you can use a digital multimeter on the sensor wiring, check voltage--ground--signal. With code 35, clean the throttle body and idle air control valve.
