Code #32: EGR System Failure.
Code #33: Mass Air Flow Sensor High.
Code #34: Mass Air Flow Sensor Low.
Did you disconnect the battery after swapping sensors? That will clear the codes. Check the wiring harness to the sensor is ok too.

Thanks for that 77CVT. I have disconnected the battery each time I change something, but the problems always come back. To date I have tried 2 maf sensors & connector I have replaced maf relays I have replaced IAC & TPS. Have replaced evrything in the ignition system, & a new ECM, have replaced coolant temperature sensor & also O2 sensor as well as all new injectors and lastly a new fuel pump! You can see why it is driving me insane! Cheers
